American IPAs are one of my least favorite styles. I can drink them, sure, chilled on a hot summer day, but that's a rare occasion. The acidic C-hop mouthful is just unpleasant to me.
That said, British IPA is one of my absolute favorite styles; Sam Smith India Ale, Meantime IPA, Worthington, that stuff is nectar of the gods! I'd say the same for US versions of the style, eg Shipyard Fuggles IPA. Hoppy but balanced, and IMO a much truer representation of what an IPA should be. The whole American IPA phenomenon seems to me to be based on misunderstandings and myths about what the original beer was like. But to each his own, I suppose.
