The Wyatt Family is simple and something that I'd personally find much more intimidating: a trio of big, burly, hairy, unwashed hillbillies comprising a backwoods cult. If I saw The Brood on the side of the road late at night, I'd think they were on their way to Comic Con or to some sort of vampire themed Cosplay party. If I saw the Wyatt Family, I'd have images from Deliverance or the Wrong Turn horror movies flashing through my head.
When it comes to mic skills, none of them could remotely touch Bray Wyatt.
As far as matches go, again, I'd easily go with The Wyatt Family.
In terms of entrance, I think both entrances fit each faction well. The Brood had the flashing lights, the ring of fire surrounding the elevated stage floor, the fake smoke, etc. and it fit. The Wyatt Family comes out with Bray Wyatt carrying only this lantern and, again, it fits when you consider that these are guys who live in a Florida swamp on a farm with no electricity.
