3DS - 9/10 - Great games and you can also play the huge DS library on it. Zelda ALBW is da best but Kid Icarus Uprising is pretty close.
PS4 - N/A. It's being repaired and I barely played it so I can't comment on it. But I think it will end up being one of my favorites.
PS3 - 8/10 - Its library lacked in Japanese RPGs and as a whole it wasn't that appealing to my tastes but it's great to play PS1 classics, and I use it to listen to music in Spotify and watch Youtube videos on the big screen :P. My fave game on this console is Ni no Kuni.
Wii - 9/10 - It has Xenoblade and many other great Nintendo games. Also I can play Gamecube games on it and the Virtual Console is amazing. Xenoblade is my fave on this console.
PS2 - 10/10 - Glorious games library. Dragon Quest 8 is my favorite PS2 game.
PSP - 7/10 - I loved KH Birth by Sleep on it (though now that I have KH BBS HD it's kinda pointless). FF Tactics TWoL was amazing too and Crisis Core was a cute prequel.
