Yes for me. I think Heart really did a horrible transformation into the 80s, but a lot of their 70s stuff kicks ass. Barracuda is, of course, a classic. For me - so is magic man, straight on, dog & butterfly, crazy on you and many more songs.
I like Mistral Wind too.
Although there are not that many contenders for the throne, 70s Heart is my favourite female fronted rock/hard rock band.
Also, rock should have more female guitar players.
edit :
My thoughts on U2 is that, although I haven't heard much of their post 2000-stuff, they suffer much more from being too popular and not cool to like than they do from lack of musical ability.
