Roy, I cannot tell you which are best. I have had Camso track systems on my Kubota RTV-x1100 for the last three winters. Definitely a bit of a chore to put on and off each fall/spring by myself, they are heavy. But, I absolutely love them. For me, it's all about traction, whether it be plowing snow or the real reason I got them, to pull fish houses on the lake. With the Kubota, it's all low and slow anyway. Slower with the tracks, but I don't mind. The traction with the weight of the Kubota is incredible. Have had instances where my full size pickup couldn't pull another out of deep snow due to traction. Hooked the Kubota with tracks to them, put it in low, and walked them right out. Amazes me how the tracks grab snow across the wide footprint. I've also run through powder as deep as 15" and floated right through it.
