They all have the same mileage, basically. Both the 2000 models have hard and soft tops. It looks like the 2001 only has a hard top. The price is very close for all three of them.
I'd go with Jeep #1. It's the 2001 model. The main reason is that it has the most information about the jeep and I like what the information I see is, too.
Bonus to me is that jeep # 1 is an auto. It's the one I like of those three.
