I think both will do the job, in real world use you will struggle to tell them apart, both are fit for purpose.
I have had 4 of the cheapy copies for a few years, cost me $220 delivered. So far they have been great and got me and mates out of being bogged. Compared to the name brand these one are clearly not as sturdy or heavy duty, in fact the 4 of mine are lucky to weigh as much as 2 of my mates Maxtrax! But used sensibly they have so far done the job. Wouldn't use them as a bridge though....
