i would go with the WIRED controller considering its cheaper, and i t would be easier to setup. You are going to want a little program called Switchblade, it helped me alot when i wanted to use my xbox controller with WoW. It configures pretty much everything for you = ] check it out here-------- i believe that there is a trial, but for the small price that you pay for the service (which i have = ]) its worth it to avoid the extra heartache of setting all of that up yourself!
hope that was helpful!
