Feature matrices are close to useless for PLM selection. All four major platforms manage parts, BOMs, documents, changes and CAD. Every one of them will tick every row of your requirements spreadsheet, honestly, because at feature level they genuinely can.
What differs is the shape of the commitment: how customisation survives an upgrade, who can make changes, how expensive it is to be wrong and how hard it is to leave. Those are the axes that decide whether you are happy in year five.
We work primarily on Aras and 3DEXPERIENCE. Read what follows with that in mind — we have tried to write the version we would want to read if we were buying.
Platform specifics — licensing structures, upgrade models, cloud terms — are as we understood them in July 2026 and all four vendors change them regularly. Treat what follows as a way to frame the question, not as a substitute for confirming the commercial detail with the vendor before it informs a decision.
1. The axis that actually matters: upgrade cost of customisation
Every PLM implementation is customised. The question is what happens to that customisation when the platform version changes.
Aras Innovator separates the platform from your configuration by design. Customisation is data — item types, forms, workflows, methods — held in the database rather than compiled into the product. Under the standard subscription, upgrades are performed as a service and are intended to carry configuration forward. Where that holds, it makes heavy customisation materially less risky than elsewhere and it is the single strongest argument for the platform — though "intended to" is doing real work in that sentence, and the exercise below is how you find out whether it held for customers like you.
Teamcenter distinguishes configuration (BMIDE data model) from customisation (ITK/server extensions). Configuration migrates reasonably; deep customisation is where upgrade cost concentrates. In the estates we have worked in, heavily customised deployments often sit some versions behind, and without deliberate investment that gap tends to widen rather than close. Lightly customised ones upgrade far more comfortably — the variable is your own code, not the product.
Windchill is similar in shape: out-of-the-box configuration upgrades predictably, Java customisation is where the cost sits. PTC has invested genuinely in reducing this and recent upgrade tooling is better than its reputation.
3DEXPERIENCE pushes hardest toward configuration over customisation, and on the cloud offering you have considerably less say over the upgrade cadence — generally a window to schedule within rather than a date of your choosing. This is a real benefit — you are never five versions behind — and a real constraint: you adapt largely to the platform's schedule rather than the reverse.
The buying question: "Show me a customer who has upgraded twice with our level of customisation and tell me what each upgrade cost them." Not whether upgrades are possible. What they cost, twice.
2. Who is allowed to change the system
This determines your dependency on outside help more than any licence term.
- Aras — a capable internal administrator can model item types, forms and workflows without writing code. Low-code by design; the ceiling for self-sufficiency is high.
- Teamcenter — BMIDE configuration is learnable in-house, but the tooling assumes a specialist. Most organisations retain a partner.
- Windchill — similar; type and attribute management is accessible, deeper behaviour is developer work.
- 3DEXPERIENCE — broad configuration through the platform, but the model is large and the learning curve is real. Partner dependence tends to be highest here, particularly during initial modelling.
The buying question: "After go-live, what proportion of change requests could our own team implement without calling you?" Ask their existing customers the same question and believe those answers over the vendor's.
3. Licensing shape, not licensing price
Compare structures, not headline numbers, because the structures behave differently as you grow.
- Aras — subscription covering platform, upgrades and support. The model has historically not charged per named user for core capability, so cost tends to scale with scope rather than headcount. The packaging has evolved over the years, so confirm the current terms rather than relying on its reputation.
- Teamcenter — tiered by role and module. Predictable and it grows with both headcount and functional breadth.
- Windchill — similarly role-tiered, with meaningful differences between author and consumer seats.
- 3DEXPERIENCE — role-based on the platform, cloud or on-premise. The role catalogue is extensive; costing depends heavily on getting role assignment right.
The buying question: "Model our cost at 3× current users and 2× current modules." Any structure looks affordable at today's scale.
4. Where each is genuinely strongest
Written plainly, including where our own platforms are not the answer:
- Deep CATIA/SOLIDWORKS estate, design-centric, one vendor end to end — 3DEXPERIENCE. The CAD integration is native rather than an interface and that difference is real.
- Deep NX estate, complex configured products, large-scale manufacturing — Teamcenter. Its configuration and variant management at scale is the most mature of the four.
- Heavy customisation, unusual processes, a wish to stay in control — Aras. If your process genuinely does not resemble the template, this is the platform that will not fight you.
- Discrete manufacturing wanting broad out-of-the-box coverage quickly — Windchill. Strong defaults; the fastest of the four to a conventional implementation.
- Under ~50 engineers, standard processes — possibly none of them. A lighter tool may serve you better and the honest answer is sometimes that enterprise PLM is the wrong shape entirely.
5. Exit cost — ask before you sign, not after
The question no vendor volunteers: what does leaving look like?
Ask specifically:
- Can we export the full data model — items, structures, revisions, relationships — in a documented, open format, on demand and without a services engagement?
- Do we hold our own database or is it in a tenancy we cannot access directly?
- Is the customisation we pay for expressed as data we own or as code compiled against your platform?
- What happens to our CAD files, specifically, if the subscription lapses?
You are not planning to leave. You are establishing how much leverage you retain — which is exactly what determines the renewal conversation in year three.
6. A selection method that is hard to game
Vendor demos are optimised. Replace them with this:
Bring your own data. Give each vendor the same three real part structures — including your worst one, the assembly with the messy history everyone apologises for. Ask them to model it during the evaluation, not in a prepared environment.
Bring your own change. Take one real, recently closed engineering change and have each vendor walk it end to end in their tool, with your approvers watching.
Score on four axes only: upgrade cost of customisation, internal self-sufficiency, cost at 3× scale and exit. Features do not appear, because they do not differentiate.
Talk to a customer they did not nominate. Ask the vendor for a list of customers in your industry, then find one not on it.
7. The uncomfortable conclusion
For most mid-size manufacturers, any of the four will work if the programme is run well and none will work if it is not. Selection consumes an extraordinary share of executive attention relative to its impact on outcome.
Data model quality, change process design and whether item identity was settled before anything was built on it — those decide success. They are the same decisions regardless of which logo is on the login page.
Spend accordingly: weeks on selection, months on the model.
