Differences between X, Sahara, and Rubi 07-10 Unlimiteds?

I'm debating on whether or not to get a JK Unlimited. I remember when I had my 04 TJ there were several differences between X, Sport, and Rubi. Now with the 07-10 4 Door models, are there any major differences between the models, like say the axles or anything for that matter. If I do decide to get a JK Unlimited I plan on running 35"-37" tires and the appropriate long arm lift and gear change to coincide. Bearing that in mind and knowing what will be staying on the Jeep and what will go in the swap meet pile, which trim level would be the best choice.

I am not an expert on JK's but I believe the guys over at jk-forum.com can help!

They have the same differences as the TJs do, it's just that all JKs have a D44 rear, but go look at the specs for the TJs and you will know the differences for the JK. The other difference is they all have a the NV241J t-case with 2.72:1 low gear, and the Rubicon JK has the NV241OR with a 4:1 low gear. I do know that 35s or 37s will require some bracing on the JK axles because they are wider so that has lead to some been tubes from the wieght with 35s or 37s. 37s maybe a little too much for D44s even on a Rubicon unless you do some trussing, even then they are at there limit, so you may just want a cheaper model and rip out the axles and go to D60s, but then you will still have to buy a 4:1 low t-case if you want it. 37s are really a bastard tire, they are too big for 35s and too small for D60s, because you have the same diff clearance with 33s and D44s as you do with 37s and D60s.
