I use the Inventor Suite (Inventor and AutoCad) at work and we are on subscription so we get upgraded every time there is a new version.

If you are very anti ribbon there is an option to return to the layout of 2009. I was unsure about this at first but when you get used to where everything is located I find it easier to use, this could be due to my usage of a rather small monitor for CADing (not having to always be scrolling to find commands saves me time). A lot of this is preference, none of our engineers have inventor set up the exact same way, the more you use it the more you will customize it to your exact needs.

The content center has been expanded and sheet metal gets better with every new release.

The new plastic tools look nifty but I haven't gotten a chance to play with them seeing at I work mostly with metal though I'm sure I will enjoy working with it when we make parts on our FDM machine next year during build season. There are a few other new features like shrinkwrap that should come in handy for robotics but I have no use for with my job.

In short if the only thing hold back from upgrading is the ribbon UI you can always switch to classic. Especially if you plan on trying to design sheet metal parts I would upgrade.

Just my opinion of course.
