I have a Mullard 6080 and like it quite a bit. Whether you'll like it I can't say.
The GE? If I hadn't just scored a pair of Chatham 6AS7G's I'd be jumping on that. GE's pretty much suck universally, at least the ones that were actually made by them. But (and a big but), the one you linked was made in 1945, the same year that GE acquired KenRad. While I can't guarantee it, with the black plates that tube was almost certainly made by KenRad before GE got settled in enough to muck everything up. I haven't heard one so I don't know how it sounds (and again I have no idea whether you'd like it), but early 40's KenRads are extremely desirable tubes regardless of the type.
I almost bought the GE but woah the shipping is $50! it is almost the price of the tube I think i'll go for the mullard....
