Yes and No. I feel that you can't beat the F80 series of ratchets for 3/8 drive. The ability to work in cramped engine compartments is enhanced with the short 5 degree ratchet swing.
However, I feel they missed the boat in the 1/4 drive version T72. The head is too thick on the T72 when you compare it to the 60 tooth Matco and other Danaher branded models, the Mac round head, or even the Snap on 1/4 round head model. If they could have cut the T72 head thickness to equal their competition, they would have a winner hands down.
Lastly, I think the 936 series may be the best balance between strength and fine teeth on the 1/2 inch drive models. 80 teeth may prove to be too fine on a 18 or 24 inch long ratchet. You don't need as fine of ratcheting action with that long of a ratchet. Time will tell when they come out in numbers. I've been using one of the new Proto 45 tooth (the one that replaced the older Big Dawg series) long 1/2 drive ratchets for a couple of months with good results.
