Disagree with the OP. In my view Patrick Stewart is not a good actor, nor is anyone else on TNG other than perhaps Spiner.
TOS has amazingly great actors across the board.
DS9 has amazingly great actors across the board, with the one exception of Terry Farrell, who is terrible. Including the very large secondary cast who's talent dwarfs that of most the main cast, and most of the main cast of all other Trek shows.
The Neelix and Doctor and Seven actors/actress on Voyager were quite good.
Enterprise's only great actors are the Dr. Phlox actor and Jeffrey Combs when he guest starred.
Overall though DS9 has pound for pound the best ensemble of legendary acting master talent ever put into a TV or movie production. No way anything else can field as large a variety of legendary actors than that all in the same production (by 'legendary" I'm talking about pure acting talent here, not necessarily popularity).
