Are you in the US? American IPAs are quite different from British or other European IPAs in style and flavour. Could be worth trying if you can find some as the British IPAs tend to be much less heavy on the bitter notes and have a rounder flavour.

I am more positively inclined to British beers like Spitfire and Bishop's Finger which, although I'm not sure they're technically IPA, are definitely quite bitter. I don't think I've ever seen them in the US, though.

I would have agreed with you a year ago, however, some of the "New England style" IPAs have been quite good lately. New England style has less hops and tastes really "juicy."

I mean, prominently advertising their IBUs would suggest that's even what they're going for.

Interestingly enough, some of the ultra-high-IBU beers come out the other end and don't taste nearly as bitter as mid-IBU IPAs, and they tend to have more actual flavor even. Something like, for example, Lagunitas Hop Stupid with 100 IBUs doesn't taste half as bitter as your typical 60-70 IBU IPA.

Hop Stoopid is one of the few IPAs I can stand, actually, which I find particularly bizarre because I normally don't like hops (I normally go for thick malty beers).

There is a limit past which you can't taste the difference (I mean like humans are physically incapable), I think.
