You are right stubble, the Gators have an almost identical tread pattern to the Mud Bugs.
The only advantage with the Bugs is that you can get them in a 25" and still have the deep lug.
With Gators if you get a 25" tire, the lug is smaller.
If a person was going to buy a 26" or bigger tire, definately go with the Gators and save some $$.
