I voted O'Brien and TOS-Scotty. Reliable no-nonsense men who get the job done.
I'm sure Geordi is a very capable engineer, but sometimes he comes across as a manager who lets his underlings do the real work from behind his desk/console.
B'Elanna.....it's a miracle she even has any underlings left, with her temper.
Trip. Well, he got the job because he knew the Cap'ten.
JJ-Scotty I can't take seriously. A barely competent clown, much like the rest of the characters in JJ-Trek.
