Yeah especially if you get the Cornucopia, anything that spawns baby balls (except shotgun...) pretty much becomes the best DPS you can do. That 50% buff pretty much puts it like way over the line of being the best in slot.
Without Cornucopia, some characters use the baby ball spawners better than others.
I think in general though, Maggot is pretty much op. I dunno many runs I lost when I'm running Maggot
