I would go with the A-Z. I just installed a set on my 05 TJ last night. The biggest difference is that the ones from A-Z give you more protection under the tub. They go in 6.5" where some of the other are only like an 1" or so. Here's a thread we have been using for discussion.http://www.gatrailriders.com/GTRForums/index.php?topic=2343.0;topicseen
