Here's mine:
Patrick Stewart tops the list. I didn't always like his character but he's a first rate actor who unforunately more often than not had to be a one dimensional character.
John Delancy is a close second to Stewart. His portrayal of the Q was nothing short than outstanding.
Louise Fletcher as Kai Wynn. Didn't always like the character but I've seen Fletcher in other TV/Movies and she's a brilliant actress.
Robert Picardo as the Dr. on Voyager and his arrogant smugness was comedy relief.
Andrew Robinson's portrayal of Garrick was brilliant primarily because he made the character to believable.
Honorable mentions go to William Shatner and Lenorad Nemoy who both played their characters well, but I don't think either of which are particularly good actors in general. Also, they are deserving of some special mention because their acting careers [especially Nimoy] got destroyed in the type casting moving forward. [Shatner some what recovered with TJ Hooker]
An Honorable Mention as well to Brent Spiner. I give this to him because Spiner in real life is so different than the character he portrayed, Data.
An Honorable Mention as well to Tim Russ who played Tuvok. I give this to him because like Spiner in real life he's completely different. He likes to play music and I once attended a show at a local tavern where he was performing and met the man. In person, he's funny, interesting, a big and a big joker. Didn't hurt as well that I find him attractive.
