Spock is the only Vulcan I've ever liked. Even Tuvok I never really liked. I think it's because the Vulcans as a race are utterly unrealistic. No being with emotions can shove emotions away like that without snapping and going totally apeshit, it doesn't work that way. Shove a lid down hard even on normal human emotions, and those emotions - which are still there - are going to ferment, turn toxic, and explode. I know this firsthand, because I had mild success doing the same thing for about 10 years, and they eventually came back on me like a pit of black acid that I'm still dealing with years after the lid exploded off.

And then, the Vulcans supposedly had even more intense emotions than humans, before they started pushing them down. So yeah, Vulcans would last maybe two or three generations before going completely bugshit and turning into a race of berserkers the likes of which would make Klingons look sane and calm, and probably blow each other to Hell until nothing was left of their species.

Lt. Cmdr. Data, at least, was realistic, never having had emotions to begin with. Though in his own way, he did kind of have emotions anyway, even before getting the emotion chip installed.
