I was in the same boat. Learned inventor way back in 8th grade, Solidworks in preparation for college. I use both for a lot of things now, but still prefer Inventor.

As far as features, they each have their own perks, but for 95% of typical use, they are for all intents and purposes identical. They're both incredibly powerful packages that get more powerful with each release. I find that people always find whichever one they were taught first "easier."

The best advice I can give you is, don't think of it as a "move." Think of it as "learning something new." I took an advanced CAD class in college in Creo, while all prior classes were in Solidworks. The professor justified this decision by saying that the ability to pick up a new CAD package is one that will serve you well in inudstry, if a company that hires you uses a program that you've never touched. She was right; learning Creo was exponentially easier for me than learning Solidworks was, just as learning Solidworks was exponentially easier than learning Inventor. This had nothing to do with the ease of use of the programs (good luck finding someone who will call Creo the easiest of the three!), but everything to do with my experience learning how to learn CAD software.
