I can't really decide for you. You need to make that decision yourself. My car was pretty quick, so I think I would have enjoyed 3.27's with the AOD. I did a lot of drag racing though back in those days, and the 3.73's made that car really fast for what it was. I had a couple bolt-ons in a otherwise stock AOD LX and was running 14.1's with that setup.
I just hated driving it around on a highway cruise and stopped going to car shows with it if it required a 45min+ ride on the highway.
5-spd swap wasn't bad really. Worse part was gathering all the parts. Second worst part was the pedals, but I've done a pedal removal a handful of times now and it's really not too bad at all.
