Namor could. His willpower is goddamn insane, he was pretty much the only one (only living creature) Doom had to take precautions against when he tried to control the world with amplified Purple Man. When Puppet Master tried to control him with the puppets, Namor concetrated...and the puppet exploded. 😑
Puppet Master was so afraid that he never dared to even try control Namor again.

You can name anyone. What it takes to work a power ring isn't exactly clear in the first place.
Back in the good old days they were easy and any old drunk that got his hands on one could create a giant beaver (it happened!)
These days apparently it hurts to use the rings and immense concentration is required
Give it a few years, the rings will be pink and only usable by farmyard animals and Canadians
😛
My Top 3 would be, Doctor Doom, Namor and Thor. All have insane willpower pretty much trumping the others.
Doom would certainly be able to make a complex machine with a ring. He'd be pretty unstoppable, since he could make anything he wishes. Namor is pretty imaginitive (he is an excellent sculptor), and Thor would have mighty strong constructions.
