I have both the Power Claw and X3 on 163 turbo Axys. The power claw works extremely well it’s hard to say witch is better. Epic deep days the X3 might edge it out a little. When tree riding and you think your stuck with the power claw it just keeps going and going so many times I’ve thought I was done off the sled rocking or pushing and and it just keeps me moving enough it just doesn’t stop
