I've given almost everything a shot. Actually more so than I ever would have, but GJ offers more options than I'd ever known about.
Shop and service bags are a mix of Snap-On Dual 80s (and one Snap-On 1/4" Roto), SK round heads and Williams USA 36T.
Home is now a mix of Williams USA 36T, SK Round Heads and my old Williams 24T (and one 1/4" Snap-On Dual 80 flex head, which may go to work or be sold).
In the past I've owned and used the hell out of Craftsman RPs, Gearwrench in 60T & 84T, Matco 88T, Snap-On 30T, MAC 30T (love the look, hate the feel), Kobalt Taiwan 72T, Kobalt USA 36T (same mechanism and slop as CM RPs).
Love my Dual 80s and SKs at this point. Still tempted to try a 30T Cornwell soon though...
