I never liked the dude on Voyager. Not Tuvok, but the other Vulcan... I can't remember his name. But he was way more open about being a dick with a superiority complex than any other Vulcan I can think of, including Solok.
I loved Valeris though. She was an important window into how Vulcan "logic" isn't a formal system of maths and proofs but a multiplicity of systems that each try to be internally consistent. I didn't agree with her conclusion, like I wasn't meant to, but I actually thought she was a very courageous person for acting on her own moral conviction.
I haven't seen all of Discovery, Enterprise, or DS9 so I'm completely unqualified to participate in this, but I'll make a write-in vote for Original-flavor T'Pring. Biiiiiiiishhhhhhh
SNW T'Pring though, I love her. She's got actual depth and I can empathize with her.
Runner-up: TOS T'Pau. Stuck-up xenophobe, plus they gave her that dumb early modern English dialogue of thees and thous that was supposed to convey ancient wisdom or something but they conjugated it all wrong and it's annoying as hell
