Randy, I did the Ocoee and the Nolichucky while I was there last summer. Here are some pros and cons:
If the water is up, the Noli should be a lot of fun.
It's more remote-feeling- it's supposedly the oldest gorge in the east- everything is covered in kudzuu (sp?) and it feels like a jungle. There are train tracks following along part of it.
There will be way fewer people. There aren't as many rapids, but the ones it has are fun.
The day I did the Ocoee, I had to wait for over 30 rafts from 4 different companies to launch before me- one of whom pinned on the first ledge drop 5 feet from the ramp, which was nice of him because it gave everyone else a cushion to push off.
Throw in the 50+ kayaks who were on the water that day and suffice it to say, the traffic jams were incredible.
The plus side is that the Ocoee is continuous Class III (they call it Class IV but it's not by Western standards and I'm not being pretentious)
The other plus is that the Nantahala is on the way to the Ocoee so if you're in the area you could hit that too- I didn't get a chance to run it, but it looked really pretty (not rowdy) from what I could see.
