You do get a little bit of throttle lag (from a combination of fly-by-wire throttle, the auto box, and turbo lag) which is most noticeable in stop start traffic but I've just gotten used to it. I'm guessing that would be less with the petrol.
The new 3.6l petrol motor is a lot better than the previous 3.8l both in power and fuel economy. It's probably still use a bit more fuel that the diesel, but I suspect that will only really be noticeable when driven hard/loaded up/towing. If you spend the vast majority of your time with the JK empty around town (sad fact but most of us do!) then the petrol will probably be OK for you.
My advice is test drive both. If you were doing loads of outback camping trips loaded up heavily, or towing a lot (for work or pleasure) then the diesel is the natural choice. If you're not then get which one feels best for you. Both are good motors.
