I quite like some Tull, I don't listen to it regularly - but Aqualung and Heavy Horses get a play every so often. MB I don't know loads about, I had a mate who was quite into them heard bits, sounded ok but not enough to grab me.
Yes I don't like, I just really can't stick Jon Andersons voice. It was odd, I bought Close to the Edge years ago, and quite liked it, lent it out and got it back and absolutely hated it! Since then they just annoy me. So it was a toss up of them and Queen who I have a long standing loathing for.
It is all relative of course, as Rob says there are many things way worse than any of these bands!!!
As for Lars Ulrich and Metallica, if you could erase a band from history, they would be one I'd consider!! Even though the first couple of albums are ok, that is outweighed by
the fact they are such a bunch of total and utter words removed. Which is why that EF hoax worked a few years back
