hard to pick one b/c each gen of consoles cant be compared as one they have there own time there own era
for ex. ie the ps2 is considered the best but its inferior to the 360 and ps3 in many ways graphics, online, achievments, games, and amount of AAA games
so all do my fav for the past few gens
3rd gen NES
4t gen SNES
5th gen ps1
6 gen ps2
7 gen 360
