I would like to point out that Tuvok is not the only prominent Vulcan who has let emotions get the better of him once in a while.
I would go further and argue that Vulcans all recognize that they are inherently emotional, and strict denialism is just part of the way they build the logical society and mindset that they desire. Tuvok is honestly the first Vulcan they showed properly dealing with that, despite his attempts to blow it off by refusing to talk about it with others.
The other Vulcans we saw tended to leave it at the surface level, and then we didn’t get to see the internal struggles like we did with Tuvok
