Custodes hands down. Grey knights are still just space marines besides the wards implanted in them. Custodes are genetically different and superior in every way. Logan grimnar killed a squad of grey knights by himself. Constantine valdor defeated Horus in a duel and was the same size as Alpharius. GRey knights are soldiers where as Custodes are warriors.
