Listed in order of "Bitchy-ness."
EMH
McCoy
Pulaski
(the rest)
The EMH scores high on many lists, but I wonder if one of the other doctors would have been able to "clean out" all the Borg device from Seven's body (going to use that as a metric), where the EMH obviously couldn't?
Phlox's would be the one on the relatively short list of doctors that I would score lowest when it came to ethics, bring into existence a sapient Human Being in order to harvest a organ to save another patient, killing the created person in the process. Also refusing to save a entire species, so that a second species could rise in a social order. Best able to rid Seven of her nanites.
McCoy is the most talented surgeon, this being his distinguishing attribute beyond the others. He is notable as a medical researcher, and he is the only one who is a profession psychologist. Second most able to rid Seven of her nanites. Plus he's charming around the ladies (dream on Bashir).
The others .... well they're kind of just there as doctors,
Crusher I've alway rated as "average" across the board, she's probably a good indication of what is the standard for doctors of her time period.
Bashir has enhanced intelligence, but where do we see him being unusually fantastic as a doctor? He's good at his job.
Same with Pulaski, there's nothing wrong with Pulaski's abilities.
