How hard does Rigo hit in comparison to Donaire?

[SUPREME.]

We all know Nonito has monsterous power, and has the ability to knock Rigo out with any given clean punch.

If Rigo catches Donaire clean could he KO him brutally?

Seeing Marroquin wobble him has me extremely worried, Nonito has one of the best left hooks in the game and could end Rigo's night if he catches him.
