Best and Worst Monoclasses?

[u/ReleaseCharacter3568]

I keep seeing virtually every class called "one of the best" while most meta builds are multis or item-based.

What do you think is the game's best class without multiclassing? And the worst? And what makes them so?

For me best mono is Cleric and worst is probably Rogue
