3DS!!!!!!!!!!!!!!!!!!!!!!!!

I'd have to say the DS. While the 3DS is great, it just doesn't have the library of games to match what the DS had. Though at least they're B/C, so...

It's hard for me. It's between GBC and GBA. I was a Gameboy kid growing up. Meaning, I didn't have any home consoles but I did have a Gameboy Color and soon thereafter a GBA. I had a few good games and I came to love them so. Pokemon Sapphire and Zelda: Links Awakening mainly inspire my choices.

Hmm, that's a good question.

I'd probably rank them as follows:

1) DS
2) 3DS
3) GBA
4) PSP
5) GB/GBC
6) Vita
7) Game Gear

1. Nintendo DS
2. GBA
3. PSP
4. GBC
5. 3DS. Disappointing to say the least.

The Game Boy Advanced SP with it's front lit screen. That little beauty folded up so nice you didn't even no you had it in your pocket. Too bad Nintendo killed it so fast with the DS.

Gameboy Advance SP is a GOAT handheld!

3DS, pretty much one of the best gaming platforms in general.

PS Vita for me. I use it much more often than my 3DS XL.

Vita because it was the only handheld system to ever deliver a full fledged home console experience on the go. It was a pity it only got a few games that truly demonstrated it.

It's also an absolute beast for RPGs and indie experiences too though.
