If you won't want to get into gearing and axle upgrades, I would stick with 33's. You already have the clearance for them, so you won't have to do any other work to make them fit.
Running 35's on a YJ or a TJ takes a good bit of work like axle swaps, gears and proper suspension setups. So, unless you're really to shell out a god bit of cash, I'd stick with 33's.
Hope this helps! Feel free to PM me if you have any other questions.
