The fun-ness is probably more or less the same. Graphics are worse (but great for being a PS3 game). Most vehicles does not have an interior view on the PS3, instead they have a camera in front of the windshield. Some vehicles have an interior when you ride as a passenger, such as the limo, the fire truck and the Savage. There were plenty of updates for the PS3, but the latest bunch of updates (for the last year or two?) have been PS4-gen only. Online: public lobbies are quite messy sometimes but if you find some friends to play with it's okay. As for if it's worth it, I guess it depends on how much cheaper it is than the PS4 version.
