AMT B-1 through Ignite Amps (Metal Test)

I really want one of those pedals but I really don't know which one to get, E1 P1 or B1. Which one is the best for rhythm metal chunk when using impulses?

It's hard to pick, haha! I love the chunk of the P-1 and the B-1; P-1 has that sexy almost "hollow" rhythm sound that I really like while the B-1 has that nice snappy type sound! Get both if possible? Haha
