The way I see it, good fuel is great and all, but I don't want to spend my time planning my trip around fuel stops. I go by the usual, try to find stations that deal in volume. If a station has only one pump off to the side that isn't dirty and I'll pass for the next one.
I've driven across the county, filling up at whatever place seemed good at the moment. Fuel hasn't made a noticeable difference in performance, but I have seen my shoot levels climb faster at times. Not sure if that is from fuel, or elevation.
