That depends on how you use your Jeep. If you use it mostly on pavement and light trail use go ATs. If you do more trails and rocks go with an MT.
The JK's have a bit wider axle width and Jeep didn't increase the thickness of the housing to compensate. If you are staying under 35's you should be fine. Most guys recommend sleeves and C gussets for 35's or larger on the JK's though. Evo sells them pretty cheap, just need to find someone to weld them for you.
