I'd say Winged C, but they went out of production and the price shot up for whatever remaining stock exists (I actually got a matched pair of NOS GE's a few months ago for less than most places are selling the winged C tubes).
I haven't tried much of the TAD stuff, but their 6L6WGC is supposed to be a good copy of the old GE tubes and have good clear bass. There's are good reviews of current production 6L6GCs here
if you haven't seen them yet.
