I'll gladly add another
Robin Curtis by a long, long, long, long shot!
I never cared for the half-Romulan concept for the character. It always struck me as TPTB simply wanting another charcter like Spock. Whereas Spock was half-Human/half-Vulcan, Saavik was half-Romulan/half-Vulcan.
A full Vulcan can be a very interesting character, as they showed with Curtis' Saavik, Russ' Tuvok, and Blalock's T'Pol.
The fact that Alley's Saavik was much more emotional than Curtis' can be explained (as has been done in this thread) by saying that she was simply a young Vulcan still working on her emotional control - Vulcans do have emotions after all, they just keep them repressed as best as they can.
And then there's the fact that I think Robin Curtis is much more attractive than Kirstie Alley.
She was one of my earliest crushes. For that alone, she's always be the best in my eyes.
