Well this is too hard! They are two totally different kinds of music. Also they are decades apart, so there is no way to really compare the,. If I had to choose which one I would rather listen to, it would definately be Guns 'N' Roses.
XCoheedX is right. They are really different bands but I think Guns N' Roses is a better band. I really like the Rolling Stones but they aren't better than Guns N' Roses.
I think if you compare their success, Rolling Stones pretty much dominates Guns N' Roses. They are both good bands. In my opinion though, The Rolling Stones beats Guns N' Roses any day.
Guns N Roses are way better. Although you have to admit that the Rolling Stones are way more of a classic and more people have heard of them then the Guns N Roses.
