When written well these guys are what I consider great in terms of concept, personality, character history, or as archetypes (no particular order):

Doom
Magneto
Darkseid
Kingpin
Luthor
Red Skull
Hitler
Kang
Dracula (Marvel)
Ultron
Loki

Ones I often like, but am not so sure are "great" in terms of the above:
Juggernaut
Thanos
Bizarro
Tyrant
Moonstone
HKH
Black Adam
Sinestro
Mr Sinister
Graviton
Molecule Man

Dr. Doom
Thanos
Mr. Sinister
Magneto
Black Adam

Bonus SBP

No particular order. Lex. Doom. Joker. Black Adam. Magneto.

They are threats in power, accomplishment, idealogically, and far and away more compelling than most bad guys.

Right or wrong Hitler has played a very big part in marvel comics.
