I have a stock 2011 with 35" tires and a teraflex lift. Love this vehicle. Slower than crap with the 3.8 V6. However, put the transfer case in 4 low and the JKU transforms into an incredibly capable off road vehicle. I daily drive the Jeep and we also drove from TX to Ohio pulling a trailer. Never skipped a beat or a gas station. HA!
If I was to do it all over again, I would find a 2012 or newer JKU Rubicon hard top for all the reasons Greg and others mentioned. 35" tires and simple lift. The 3.6 V6 has 285hp which makes a huge difference versus the old minivan engine in my 2011 making 200hp. Put electrical tape on the door latches to eliminate door rattles and enjoy.
Here is a pic of my JKU...
