In your opinion, what's the most powerful class in the game?

I got surprised with how many different opinions people have about classes being overpowered or underpowered in 5e, and yes, opinions are different, but usually there are some consensus/mathematical balance with the numbers, so I got curious and looks like an interesting experiment to do. What's the strongest class? The one that is useful in different context or tiers?

Please, let your vote here and if you want to, leave some review about why you chose this class, a class you think is underpowered etc.

Leaving my own vote: Wizard. A lot of usefulness inside and outside of combat, it's spell list + the amount of spells already is strong, but some subclasses like chronurgy and divination makes them even stronger.

I would make a pool but it cannot have more than six elements :/
