Pspgo fully hacked, the only handheld you will ever need.

odd that I'm the 3rd person to say psp... but only second vote it has :o

3DS zero contest.

Absolutely the best handheld I've ever owned.

Nexus7 2nd gen. Lots of games and emulation.
Owned GBA SP,PSP,3DS, in the past. PSP and 3DS hugely disappointing. PSP like PS1- 1 analog. 3DS, too many rehashes, disappointing E shop. GBA SP was pretty decent though.

When grading my handhelds i only include the console's own library and i think alot of people are throwing the classics from older consoles (only reason why i think the PSV can even be in this conversation) in with their picks and if i did that the 3DS by far would bury the rest with it's backwards compatibility with the DS and it's eshop classics. So here's my list.

DS
GBA
Gameboy Color
3DS
Gameboy

My top 5 which could change during the lifespan of the 3DS (more rpgs!) and PSV. (if it keeps getting some of the gems it has had lately)

3DS kicks so much ass. In a few generations I predict it will be remembered as one of the greatest consoles ever made. Glassless 3D despite being "useless" for many is actually an useful and innovative concept, specially for a handheld.

I voted 3DS <3

DS is my favorite handheld, and will most likely remain that way. given with Bravely Default 3DS is slowly gaining points. (I could have said 3DS because it plays DS games, but I hate that answer.... I don't pick a console because it can play another console games).

Vita is the coolest system around when it comes to power, visuals, screen size, etc... However its no secret 3ds has better games and more of them..

Vita is the best handheld I've ever owned.

That said I voted 3ds cause of the games.

Tho by the end of May, Vita might win out.

Vita. Just love the hardware and the creative games that are made for it.
