Best (in no order):
PS1: too many great games, innovative and charming
SNES: maybe the greatest I have played, just because it has many of my favourite games of all time (FFVI, Super Metroid, Chrono Trigger, Demons's Crest, etc)
PS3: It's been a lot of time since I enjoyed so much a gaming system. Not the best, but maybe getting there
Worst (not actually bad, but didn't enjoy them so much as others:
N64: overhyped, few really good games...actually few games, and expensive as hell
PSP: few games and ankward to use
PS2: despite the huge library, I can pick only a few games that I really liked, but they were really good (MGS 2-3, RE 4, FFX-XII, among others).
The NES would be in beetween the best and worst.
I owned other consoles or had the chance to play them that I really disliked, but for me don't count because I played very little with them: Gamecube, 3DO, Wii, Gameboy, DS. All of these I would put them lower than my "worst" though.
