I can't compare brands, but I have the Remora Pro and I LOVE IT!!!! I can adjust the collection cup (incase I go outa town and can't empty it, but I still want to skim). I have the HOT (hang-on-tank) version, not in-sump. Oh yeah, you should know (I wish I did) that the surface skimming box for the "upgraded" pump (mag-drive, I think), is BIG. It's 8 inches tall X 11 inches across X 4.25 inches deep. So make sure you have the room for it!! I don't know the dimensions of the one that comes standard.
