First of all, the bands listed above are not glam rock, they are glam metal. This terminology is required to set them apart from the first wave of British glam (David Bowie etc.) True, the bands listed above are not metal (they're hard rock), but they're closer to metal than Bowie et al.
(Silence, Bowie fans. I know he did some metallic stuff.)
So here's what I think about them:
Kiss: great, great band.
Poison: had their moments.
Cinderella: very good band. Underrated by most.
Skid Row: some good songs, but I can't forgive them for "I Remember You". Yecch.
White Lion: so-so. Some good songs, great guitar player (Vito Bratta).
The rest on that list (Slaughter, Winger, Warrant) I cannot stand. Winger had a good guitarist (Reb Beach) but he couldn't save a lame band.
Right now, by coincidence, I'm listening to the king[sup]1[/sup] of all hair metal bands: Motley Crue. I'm also a huge fan of Twisted Sister.
[sup]1[/sup]I do not consider Kiss to be a hair metal band, because their origin is several years before the other bands named, and they made their mark long before the 80s LA hard rock scene took off. Also, they're from New York (as is Twisted Sister), so their inclusion in this group isn't quite right. But if I did consider Kiss to be a hair metal band, they would be the kings.
