PS5 (great backwards compability with PS4 and great exclusives already. Lots of games run at 60fps)
PS2 (great backwards compability with PS1 and great exclusives as well as LOTS of games. Lots of games run at 60fps too)
PS4 (great games but sluggish CPU, lowframerates and long loading times as well as no backwards compability)
PS1 (good first console)
PS3 (Sonys only real miss - an awful console with bad framerates, long loading and lots of misses from first party)
