I don't any experience with Jeeps, but I have read of quite a few folks who are not real happy after buying the Rubicon, the main problem with those folks is the very low low-range in the transfer case. It is really good for rock crawling, but it is too low for moving through sand, mud, etc. The Dana 44's seem like a great deal, and the air lockers engage only a low speed, but that can be bypassed.
Enjoy!
