I enjoyed his 80/90's series, it played as much as a roaming adventures through the alien landscape. I'd enjoy seeing some of the heralds again. I feel Gabriel never got a fair shake, last I recall he had been integrated as the AI of Galactus' ship.
He does have the 'all-powerful' syndrome but hey, Superman, Thor and Hulk do as well. Those conclusions are just as foregone are they not?
