Both of their respective hungers are insatiable, thus making them = in that respect.
However, in terms of 'hunger feats', Unicron actually devoured an entire universe + the stuff of space itself, on panel. Whereas Galactus could have potentially devoured all in existence, but stopped before even one universe was consumed.
So, as far as "who's eaten more" - Unicron ftw.

Which one of these Planetarians has a healthier appetite?-BONUS:
They both spot the same planet and are both starving. Looks like they're gonna fight over it. Which one gets to satisfy their hunger?
