I'd like to give you a proper answer, a normal one.
Don't mind these people, they want to extend things. Anyway, the 3DS depends on your genre. Search for the genre you're interested in. Use GBAtemp's resources for an example.
Try this thread:

And if you're thinking to get the game, view trailers on YouTube or some other video sharing website you use. There may be reviews from fellow tempers, which can be found here:

In my honest opinion, get the 3DS. The 3DS is a truthful system. Nintendo and third party companies of game developing are completely accurate on what they give us for a preview on the games, and the games are really well developed.
View trailers and previews of the 3DS on YouTube, I find more stuff over there.
