The seven Wudang heroes are some of the most memorable non-main characters I've ever seen... they're just so well-written and acted. They don't get very many scenes, but yet you manage to get to know and love them!
CLH '84 is also a fav of mine, that was all Michael Miu, and he was amazing, but I have to admit, I'm more a Tony Leung fan (when he won a Cannes award in 2000 I felt triumphant... that my, at that point, 15 year fan-admiration of him was finally shared by a beyond-Chinese-language audience!).
I was also a huge fan of the 1979 CLH starring Adam Cheung in my childhood, but that one was more a childhood thing that hasn't withstood the test of time since I've gone back to watch it again.
My love of HSDS '86 is explored here in a review that I (with a fellow HSDS 86 fan) wrote in 2005 for spcnet:

I also have HSDS 2000 and HSDS 2003 reviews here at spcnet, both versions of which I liked.
But yes, I'll probably be watching a little of this new Condor Heroes to see how they capture the 4 (5?) Greats, although the HQG from the TVB version is, in my opinion, probably impossible to beat.
