I'll put in my 2 cents here (may be worth less then that!)
I have the factory boards on my X and I really enjoy the look...but I don't actually use them to get in and out of it. Mostly I just get my pants dirty getting out, granted I could keep my X cleaner or learn to jump out further to avoid that, but that's not always an option. I will say that they are nice to have when you're washing the X, they help to reach the middle of the roof
