I think the Tamura point is interesting, because while there isn't really a traditional heel/face divide in shoot-style, I do think there are angles by which you can see him as the protagonist and antagonist of matches (for instance, for the case of the latter, I think of his 97-99 matches with Kohsaka and Yamamoto).
Anyway, as far as wrestlers that I love both as a face and heel (or tecnico and rudo, for the luchadors): Danielson, Funk, Flair, Kawada, Austin, Panther, Styles, Tanahashi, Satanico, Piper, Bret, Otani, Punk, Windham, Savage, Zbyszko, Akiyama, Moxley, Christian, Hokuto. I'm sure there are plenty I'm forgetting, and I know someone like Buddy Rose is missing simply because I haven't seen his babyface work yet.
