>>76402321 (OP)Bruce Lee was:
An excellent self-promoter
A good actor
A pretty good martial artist
A fighter of unknown, if any, capability
Seriously, he had almost zero documented fighting track record. The closest to a sanctioned fight was a tournament when he was 15, or some shit like that.
Martial arts were in their infancy in the West at that time, so you could say crap like "these are killing techniques, that's why we do non-contact sparring and kata only" with far less scrutiny. Bruce Lee was fast, we know that much. He also evidently had fair power behind his strikes, but arguably no more than a trained boxer or kickboxer. But as he says in his own movie, boards don't hit back. There is no evidence at all that Lee could take a hit without crumpling, or escape a hold, or whatever.
Dying young is arguably the best thing that happened to him: it allowed him to never once have to live up to the persona he had created.
