main rule: to each his own.
But ... IMO ...
Rosemary and sage is traditional for stuffing in poultry (along with thyme). I like them together for this purpose. You also see them togther in some other Italian dishes, but usually with a lot of ingredients so you don't really taste them alone.
Oregano and cilantro are very common to many mexican and s.western dishes. IMO, it's yummy. But again, they are usually combined with other things like cumin and chiles.
Cinnamon/nutmeg/allspice and mustard -- sounds like jerk seasoning!
Anything and tarragon, just because I don't like tarragon.
Particularly venomous sounding would be: tarragon and cilantro
and tarragon and cumin.
Also, basil and cumin
sounds yukky to me.
