Classic CJ for me. I actually think the JL grill is pretty nice looking, but those hideous fender lights ruin it. When I get one, they will be the first thing to go.
I agree with the OP. I think it's the angle of the front windshield that makes the profile of the 2dr jeep look a bit off, especially compared to a TJ. The extra length of a 4 door offsets that angle a bit. That being said, it wouldn't be enough stop me from getting a 2dr if I wanted one.
I've been thinking about switching out my LJ for a JLU or JT and keep going back and forth, but if Jeep made the J6 concept with gladiator suspension, I'd have ordered it yesterday.
