Both don't have many good games at the moment. But still, I prefer Little Big Planet and Uncharted Golden Abyss over anything on the 3DS. As for remakes, once again, I'd have to go with MGS2+3 over Ocarina of Time.

3DS:

Kid Icarus
Pushmo
Mario Kart 7
Super Mario 3D Land
New Super Mario Brothers 2

Vita:

LittleBigPlanet
Super Stardust Delta
Mutant Blob Attack
Uncharted Golden Abyss
Unit 13

Right now I prefer the 3DS' library (Though i was tempted to go with the Vita just for LBP alone). However i think the Vita library is much better then the 3DS' was in the same space of time

Gravity Rush (TGS GOTY)
RO
Soul Sacrifice
Miku
AC 3 Liberation

I don't even own more than 5 games for Vita or 3ds lol.

Vita:
Uncharted:GA
Gravity Rush
Wipeout 2048
Hot Shot Golf

3DS:
SM3DL
Kingdom hearts 3D
Kid Icarus

There are some other games for 3DS I want, like NSMB2, but since I don't own them, I won't include them.

Well, many people prefer Uncharted over Zelda and LBP over Mario, which imo its bs
if you ask me, what im supposed to tell you?!?!?!?
im a Nintendo guy so i will always see Nintendo as the right choice if you are looking for better games........but what makes a game better? oh man......thats another, rather long, story ;)

Vita's Gravity Rush, Uncharted: Golden Abyss, Super Stardust Delta, Persona 4:Golden, and Little Big Planet PSVita trumps anything that 3DS could offer. Not a fan of Mario games period which eliminates more than half of any decent games on the system. Pokemon would be a winner for me, but that is just one game, refuse to get it just for that.

I have a question for those who say that 5 10 score games is better than 10 8 score games
What do you think it was better, the N64 or the PSX?

Zelda: Ocarina of Time 3D > MGS: HD Collection
Kid Icarus: Uprising > Unit 13
Resident Evil: Revelations = Uncharted: Golden Abyss
Super Mario 3D Land > Little Big Planet Vita
Kingdom Hearts: DDD < Gravity Rush

I own and have beaten all of those games and I prefer the 3DS line up. Also those 5 listed Vita games are all I care to own but I have 6 more games for the 3DS that are all better than my worst Vita game, Unit 13.

Edit: Ok I have not beaten LBP Vita yet because I really don't like to play a platformer via analog stick.

true, its just up to personal tastes, so theres no point here and this thread should be locked then?

according to Meta and GR the 3DS wins, thats the most objective opinion we can giveç
my opinion? 3DS wins by a thousand mile

Those are the most biased users in the site. Seriously, for them, Vita is objectively better.
