Your Favorite PSP

I've only tried three PSP versions; the PSP 3, PSP GO, and PSP Vista. Of the three I really enjoyed the PSP for a few reasons; the first being that it was small in comparison to the other two aforementioned versions. Secondly, the PSP 3 is inferior to the PSP Go is something to be expected as it is an earlier version, but the PSP Vista failed in my opinion because they just started adding a bunch of stuff and removing something as core as the method of reading games. So the PSP Go takes the cake for being slim, slick, and satisfying to play on aesthetically.
 
I loved Motorstorm: Artic Survival. I could never get off that game and thought it was leagues ahead of the 360, PS2 ones.
 
PSP Vista was a complete waste of resources. They shouldn't have done anything with its development in my opinion. I had everything I wanted in PSP Go, so it's going to be my favourite PSP version.
