Well, if we're talking about powershifting...over the last 50 years, I've had Toploaders, Muncies, T-10s, a T-5, a T-45, and numerous A833s in 23-spline and a couple 18-splines.

Of the bunch, the T-10 was my favorite for that; like throwing a switch.
The yardstick, as exemplified by the Greats like Ken Dondero & etc, is no RPM flare, just next gear.
The Tremecs and 833s require, for me at least, a more - shall we say - hostile attitude...
