I haven't gone either way yet, but here is my $.02 worth.
I think top-end is cool, but very unusable... Not only do you need a lot of straights, but no police, no wild animals (in cages and on four legs), and perfect roads...
I prefer hole-shot, only because it is more usable from light-to-light and on the twisties. Not to mention, if you are going to the track you prolly won't see the uppermost top, and will always be wanting some decent jump after the apex. Plus wheelies should be a hair easier (as if they aren't already).
Finally, adding a tad to the jump, prolly won't take that much off the topend anyway. Ask yourself... What do I do more often? Drive 198MPH, or launch and drive fast!
