This might have made a good No Right Answer but I doubt it would ever happen so I'm asking you! There's a huge list of games so I will have to have to be selective since there's only 8 options, so be gentle if I don't include your favorite.
I would go for either Judgment Rites or Bridge Commander, or preferably both. The former just edges out Final Unity for personal favorite and richest portrayal of the Star Trek universe, and Bridge Commander was by far the best representation of the kind of slow, tactical combat you see in the TV show and movies - BC actually gave me a huge appreciation of the strategic depth of ST combat which isn't always used to full potential in the show. The Voyager game Elite Force was pretty great which was really surprising for an FPS, and it remains one of the most enjoyable shooters I've played. It's a pity DS9 never really got a decent game under its name, only a bunch of middlingly average ones.
As for worst, well there are plenty I haven't played especially ones from the 80s but I thought Bethesda's Star Trek: Legacy was pretty awful. Star Trek: Borg would have pretty much sucked without de Lancie, although the idea was good it was just frustrating and annoying gameplay-wise.
Anyway, over to you. Make it so!
Edit: Since the poll options are limited, I have added a full list of ST games on a user's suggestion.
