My favorites from the old series were Scotty, Spock, Chekov, Bones, Sulu, Kirk, and Uhura.
My favorites from TNG were Data, Picard, LaForge, Dr Crusher, Worf, Troi, Yar, Riker, Barclay, and lastly Wesley.
I haven't really seen much of the other two series because I couldn't get where I live for a long while, but I'll try anyway.
For DS9, O'Brien, Odo, Bashir, Jhadzia, Capt Sisco, Kira, and Quark.
For Voyager, Torres, Kim, Tuvok, the Doctor, Paris, Janeway, Chacotay, and Neelix.
In general, I notice engineers and technicians come high. Maybe, that's why I'm training to be technician.
Some of the exact orders are debatable, but it tough on some of them.
