If UHMW is buoyant (which I have absolutely no clue), it would aid in keeping it afloat in next year's water game...
Other than that, it's pretty much traction. Also, there is less "rock" to the chassis as 2 sets of wheels are lowered instead of just 1. This could make the turning a little more stable, but I don't really think it's too big of an issue.
I would recomend going with 6wd, with a couple idler wheels that don't contact the ground to avoid rubbing on the bottom of your frame on a ramp (that is, if there is a ramp.) 8wd is really just a design choice. There is an added coolness factor as well which I think should be factored into any design decision.
