I agree Banshee has very mixed reviews, but I can't remember people saying that Diamondback is a bad hyper overall. Personally, it's my favorite hyper, but the back seat has developed a distinct rattle.
EDIT - I read this thread in reverse chronological order today, so...
I think The Beast has more mixed reviews than both of them. But, COVID is a conspiracy to make the ride less popular, since only the rough seats are available.
