I'm not sure what you are actually interested in knowing.
Are you asking about whether a PADI Divemaster is a desirable person for someone to hire? In that case, I think it's going to depend more on whether the dive op or shop is a PADI operator or not than it will on the perceived comparative value of the PADI cert as compared with others.
If you are asking whether anybody you dive with will be impressed that you are a PADI Divemaster, I can tell you from personal experience that the answer is probably no.
If you are primarily interested in what training you can take that will make a polished diver out of you, a divemaster program is not going to do that. DM classes are focused more on guiding or teaching than on improving your personal skills. If I were you, I'd look for an instructor with cave training, and do some work with that person. Whether it's a PPB class, or cavern, or something else, a cave-trained diver is likely to work with you on improving technique.
