Well there's not many choices In the 4 seat sport world, rode with a rzr pro 4 seat the entire weekend on zillas and did everything he did. But the best 2 seat if your serious is either a rzr s or the can am xcr. After this week I'd buy a 4 seat even if I rode alone. The length and storage provided is irreplaceable. The talon x on some 32s on a 2 seat would be a very maneuverable quick whip. The krx as it sits is a solid choice if you want more show than go. Its benefit is being able to put 35s on factory. But 32s are all you really need for anything other than crazy mud. But the real difference between them is mostly the driver. It takes crazy stupid hills to even make a difference like splitting hairs.
