The great thing about the way Brooks plays Sisko is that no matter what he's doing he looks completely into it and like he's enjoying himself. Needs to be a Klingon? He's really into being a Klingon. Needs to be Gabriel Bell? He's really into it.
I'd say Voyager has more weak links than them. I never found Torres or Paris very convincing. I think its only particularly strong links are the big three.
Definitely agree with that. Heck, I think Sisko was a better Klingon than Worf was,
And I don't even think we need to mention Voyager in a discussion about best casts.
