I had the 50" Walker Evans RZR and will say it was a more comfortable ride due in large part to the seats and the spring/shock package. As far as trail riding (which is mostly done here) I will say I believe the 500 is more nimble and has the shorter turning radius. The only time power is an issue for me is steeper long strip mining roads. I will say it doesn't run out of power but you need to learn the gearing. The main reason I went to the P5 was the maintenance on the RZR...as someone stated...with the RZR I had to grease every weak or suffer the noise....and greasing that U-joint under the seat wasn't fun. I will say the only thing I wish they had for this was a shock/spring package...I will say having a dry seat after a creek crossing helps with this machine too-LOL
