Aluminum doesn't rust, dents more easily than steel, and can grab on rocks a bit being softer than the rock. It's also lighter than steel.
Steel slides over obstacles almost as well as plastic, and better than aluminum. Once scratched it can rust, but not hard to deal with.
I agree on the plastic skids being easier to glide over obstacles, just to bad the mfgrs want to cheat on the support behind the plastic skids. I guess mine work well due to the added support from my plow mount behind the plastic skids. Have a friend that "upgraded" all his to fancy aluminum skids, what a waste of money, they are all mangled after only one season, he has to remove them after a hard ride to straighten them out and repair the mounting holes.
