Driving characteristics with Torsen 2 vs Torsen 1?

I recently went 4.10 T1 to 4.30 T2. From what I've read, the T2 had the capability to be set up for significantly more torque bias than the T1, but no one spec'd that in any of the major applications, like the Miata, S2000, the LS1 F-Bodies, etc. which makes the two types that much closer in performance than they could theoretically be.
I don't autocross (yet) but I noticed that the car definitely felt different in the rear, smoother on throttle lift going into corners, easier to power out. I may have no idea what I'm talking about. The extra 5% power everywhere is awesome NA. Will probably hate it if I go turbo.

Sorry to bring this back and may be off topic here but I'm getting this feeling of ignorance on my part. Why no one use T2 with 4.1? Are they not compatible? Or no one likes doing this?
I had an open diff on my 95 and bought a used T2 diff to put my 4.1 gears on. That was like a year and a half ago, about 3k miles and ~8 autox's. Everything seems fine to me.

Most (like me) just buy a used diff and put it on the car. The most commonly available used Torsens are the T1 that came on NAs with 4.1 gears and the T2 that came on NBs with 4.3 gears. There are other gearings that came on special versions, but they are harder to find and usually more expensive.
I've got a T1 on the Silver car (replaced a VLSD) and a T2 on the Red car (PO replaced an open diff). They work. Laptime improvements come from seat time.
