So if you run 2.73 gears in a stock ratio 6R80, you'll have similar ratios as the modified 6R80 transformed into the 4R200 running 4.10 gears. It just seems sooo much easier simply running 2.73's than modifying, (and paying for) the 4R200 which will almost mandate a gear change if you're currently running a 6R80 also / anyways.
Just trying to figure out the "WHY" on the 4R200 is all. Here's some quick hard numbers to consider. Both transmissions on 7000rpm input shaft speed, and a 28" tall tire
6R80 / 2.73 rear gears, 7000 engine rpm 28" tire
1st - 51mph
2nd - 91mph
3rd - 136mph
4R200 / 4.10 rear gears, 7000engine rpm 28" tire
1st - 52mph
2nd - 92mph
3rd - 142mph
