Tread is grippier than VersaWheel is grippier than Colson. Which leads directly to Colson being more durable than VersaWheel which is more durable than Tread. In my opinion, and from what I've seen, the difference between Colsons and VersaWheels is greater than the difference between VersaWheels and tread. Also from what I've seen, the white KOP wheels perform very similarly to VersaWheels. I have no data to back those statements up, but that's what I've picked up on.

About bigger wheels providing more traction: the diameter of the wheel has no noticeable effect on traction, but the width absolutely does. So doubling up on traction wheels to create 2" wide wheels will theoretically double your traction. Will you actually get twice the pushing power? I doubt it. But your traction will increase significantly.

EDIT - Andrew's post reminded me that W pattern VersaWheels are a thing. I've never used them. I don't think I've ever seen them in person. So everytime I said VersaWheels, I meant specifically the Diamond tread.
