The only one? Everyone I know and everything I've ever read has leaned towards it obviously being their strongest work. Press really gushed over it, to the point where I saw it in plenty of top 5's.
I heard a good explanation recently where someone compared them to The Bronx, saying "Bronx came right out of the gate with a fucking incredible record, whereas Cancer Bats first one didn't break much ground, was a bit of an oddity and they've just gotten better and better with each release".
I'm looking forward to how hesher metal this one will be.
