That's a matter of taste, really. The 3DS still has a lot of catching up to do in the "games that I enjoy" department compared to the PSVita, I've easily clocked way more hours on my PSVita than I did on my 3DS. To be honest, there's only four games* I actively play/ed on my 3DS compared to dozens on the PSVita, so hey!(...) slim to none in the game department.
