As an opinion piece, this is fine. You have a clear preference and you articulate your feelings well, even if they are a bit contradictory. But this is a poor buyer's guide. Many of these games you've never played and you toss in things like "some lame garbage like Mario Kart Wii." A buyer's guide should point consumers to the systems and games they enjoy, not force a point-of-view onto those consumers.
For example: If you like a wide selection of indie titles and already subscribe to PS+, go for a Vita. If you're into 2D platformers and Nintendo first-party software, 3DS might be the right choice.
NOT: If you like all these bad-ass, awesome games, then buy a Vita. If you like garbage like Mario Kart, I guess buy a 3DS.
Also, Resident Evil Revelations and Retro City Rampage are both terrific games :P
