actually SA has more jumps than VC, how? LOOK AT THE FUCKING SIZE OF SA! VC covers like just Los Santos and country area.
the physic's
SA has very noice handeling but some of the vehicles arent close to the real life counterparts, but most of the stunting vehicles are close to the VC versions but the bike handeling is different, by far i do like the SA style because you can preform a backflip360 without bailing like in VC, but yet again VC made it harder, thus way more fucking fun.
Graphics
well, for me, i like SA better, nice'r weather, different areas have different weather. but VC has the most beautiful weather for making stunt videos becuase of the pure blue sky's, while in SA there is always a littlebit of fog with the blue sky's and wtf is with the white sea when its raining/dark?
Popularity
SA still gets owned by VC
