Great posts RED MX5!
For further reference, I drove a 500 hp Camaro for this past season at autocross. It had a little more trouble than a stock S2000 trying to find traction, so small diff changes made for a big feel difference.
We did most of the season with a T2R diff. It was completely seamless in every situation. Never once did we get inside wheelspin - either both were gripping or both were spinning. We had a problem with that axle so it got pulled and the stock clutch-style diff was dropped into the car. Lots of inside wheelspin, but it was actually easier to keep the car straight under power as the spinning tire acted like a fuse to keep the outside tire from being overwhelmed. It felt way slower but was a little faster as we spent less time chasing the rear end.
I think the type of diff is less important than how much it will lock up. If it will lock hard enough to break the loaded outside tire free, it's going to demand more precision from the driver. The stock S2000 diff can just break the rear outside tire free with a completely stock car. Add in stickier tires and the inside tire starts spinning before you've reached maximum traction.

The ring and pinion was going on that axle, but we had a championship we were trying to win, so the owner told me to go hard anyway during the last event. Result: http://www.youtube.com/watch?v=Qd6icOF1MV8
