If Marvel had a 'Trinity' (like DC's Superman, Batman and Wonder Woman) who would you pick as there best three to represent it?

For Example;

1. Thor, Captian America and Ironman
2. Spiderman, Wolverine and The Hulk
3. Ironman, Wolverine and Spiderman
4. Ironman, Mr. Fantastic and Cyclops

^ Those are the popular/obvious choices.

Or perhaps two of those guys and a girl. For example;

The Invisible Woman, Jean Grey, Ms. Marvel, Elektra, She-Hulk, Rogue, etc...
