First of all - if you have Inventor, you can do everything to get a shop running - 3D-Models, 2D-Drawings, 3D-&2D-Exports for the shop or the customer documentation, even basic animation, cooperation within a workgroup
1. Intuitive interface - i can get all the basic functions to good use, just clicking through them (context sensitive right mous button menues), or reading the help-files or just going on youtube.
Only the more complex functions are sometimes demanding - but it's still easy, compared to others (creo, i'm looking at you...)
2. Easy acces and handling in large assemblies, with easy selection tools (frame), visiblility settings (isolation) and memory management tools (suppressing elements / express mode).
3. I like the customizability via the API an the openly available documentation. There is a SDK within the basic Inventor package, with templates and everything to get startet in customizing Inventor. This goes hand in hand with other Autodeks-Products, like Vault (PDM). If you can code in vb.net or C#, you can customize Inventor.
4. Sheet metal modeling is nicely done and very quick - what you see is what you get, make an unfolding to check it - export any selectable surface geometry to dxf do fabricate it. Some Systems have some more specialised functions, but i can still do much more in inventor, than my shop can fabricate with laser-cutting, punching, bending and welding - i do not need more.
5. The content center, which is the out of the box standard-parts-catalog, is very powerful when using standard parts. (Creo has nothing to compare - at my workplace we have additional software, that is a pain to use, compared to Inventor Content Center.)
6. You do not need specialised drawing personel, to make drawings - any engineer will be capable of doing that. (Sidenote - Drawing personell is needed though, because engineering is not doing the drawings in the first place - it is designing, modeling and calculating and then checking drawings ot ensure fabrication quality. At my workplace we primarily use creo - making drawings needs specialised personel, because of the really bad useability of creo drawing tools.)
1. I hate the later licensing models. I want to own the tools i use, not rent them. Inventor is a very good product, but this licensing calls for punishment...
Was supscription not enough?
2. The Content Center Configuration needs work on its stability. Especially the Excel-Based table editing tends to freeze on larger tables. And the updating of table-generated parts causes some really non-discriptive error messages.
3. Cabeling and wiring is not useable with the Item system in Vault Professional (Inventor 2014/ Vault Professional 2014). Properties of single wires of a harness are not translatable into Item Properties in Vault.
Do not trust any salesperson - get a test-version and try the online tutorials with valid personell.

If you decide for Inventor: don't ever take anything as impossible - there is a powerfull API and a very helpful documentation and community!
I am a former User and Administrator for Inventor and Vault of more than 10 years. I still have access to a workstation with Inventor 2016 on it. My first employer had Inventor in the first place. My second employer had Pro/E Wildfire3 & ProIntranet 3.4 in 2012 and was planing on the upgrade to Creo 2 with Windchill. I challenged this plan with the alternative of Inventor 2014 & Vault Professional, wich was taken after several reviews and benchmarks.
Within that project I implemented a configuration to fit the regulations of the german rail industry (FSF-Documentation). The company still uses Inventor and Vault and I never heard any complains...
At the moment I am forced to use Creo 2 - and try to implement Windchill. I see now, what could have happened at my old employer and I would not change a thing.
