I'd say most of the 80s bikes had decent drum brakes. Yams, T/S or mono are good, ditto Hondas and most of the European bikes had Grimeca I think, which also work well. They had better feel to them and generally worked when wet, unlike 70s bikes. I guess a lot can also depend on the material used for the lining, of which there is probably a lot more choice nowadays.
I've fitted a TY T/S front wheel to my Ossa and it went straight in with just a new spacer made to fit. It works much better than the Ossa brake, although the bike itself isn't really suited to clutch / brake style riding.
