To answer the poll question, JL for me. BUT, I don't see me in one for a while. I remember getting into a JK when it 1st came out and was very disappointed but now im in a '15 and loving it. Its not worth it for me to jump to the JL...yet.
Looks as the spare is much closer to the body. Also, the "sahara" tire looks to be smaller BUT the tire sits lower on the bumper than the KO2. The brake light looks to be about the same distance from the top of the tire on both jeeps. Adjustable mount?
