Lotta good stuff in here, and a few confused people. It is hard to pick one "best," but I think a lot of these bands deserve mention in the top tier status. I would add Cheap Trick and their first three albums. Listen to them if you haven't. They were yuge at one point.
Also, Aerosmith - Get Your Wings, Toys, Rocks. You might even be able to argue for Mirrors, Vacation, and Pump, but a lot of people would fight you.
Van Halen - Probably their first three is the safest bet.
Megadeth - Peace, So Far, and Rust would work.
I'm sure I will think of more.
Queensryche was a good call.
The Who definitely. No discussion really needed.
Iron Maiden - pick three of their early albums. I love Powerslave, Somewhere in Time, and Seventh Son.
The Doors, definitely.
Soundgarden, yes.
GNR - Lies, Appetite, Illusion(s) definitely belongs there. Lies is a great album. If you don't like it, you don't understand it. I still play the fuck out of that album, and always at full blast, because my neighbors love it so much. They don't have rock n roll where they are from.
There are quite a few more top tier bands, even though putting out three consecutive solid albums is not easy.
