Your favorite rear end/final drive ratio and why?

If I was to gear it, if I ever planned to take to the track now and then, I'd pick one of the gears to reach hp peak rpm at peak mph and say I didn't want 4th to be that deep it would be 3rd, if it was never to see the track I gear it to hit hp peak at mph I'd want to crank it to once and while eg. 80-100 mph in second or third. Probably 100 mph in 3rd.
