I have the Cherokee with the V8 Hemi, no SRT. It has LOADS of power. One of the few vehicles I can put right up my road w/o having to use 4WD. My neighbors are from Naples and have rented just about every basic 4WD SUV on their trips here (they fly into ATL and rent an SUV). He drove the Cherokee and loved it.
I also have a Wrangler - it's my sportscar. It does need the 4WH to get up the road and struggles even with the V6.
I didn't test drive the Commander - I didn't like the looks of it then but it's grown on me a bit. I also didn't test drive the SRT Cherokee because it's front end is too low. Heck, I've already knocked off the front bottom of the Cherokee
I leased the Cherokee - $43K IIRC. The dealer here had the SRT at $500 above MSRP at the time - a little over a year ago.
