Better? Beating an undisputed or winning each belt separately?

Which would you say is a better way to become the undisputed?

Defeating an undisputed or winning each belt separately?

[Jack Napier]

separately
that's 4 wins as opposed to just 1

[Alx.]

separately, beating every holder in the division to unify is better

Beating 4 title holders ensures you're fighting the top fighters in the division and earning your right to be called the best instead of just getting a shot ala David Haye without really proving yourself.
