What's the best type of Wizard?

Any type with an identity beyond just 'does magic'. The generic wizard is bland and boring by this point.

> Undead are immune to that. What's your AC?

oh fugg. you got me there.

Arcane Trickster

Fizban/Zifnab

One who's a fan of Ronnie James Dio.

...

Swords&Sorcery baddies.

Crabby loners with a large toolbox, but who fallback on trickery, and who only interact with society as a whole at it's expense.
Bonus points if the moral implications of their actions never even cross their mind.

One that harnesses some source of power, rather than just studying incantations, which colors the magic they use.
