I think Soundgarden are overrated (here we go again with the 'rated'). I think their only moment of greatness is Superunknown. It is, I will admit it, an amazing record. Down on the Upside was great in places, overly downbeat and humble in others: they'd forsaken or lost something by that point. Louder than Love and Badmotorfinger I think are just pretty awful: big dumb loud Led Zep metal with lots of shrieking and testosterone and delusions of grandeur: the video for Rusty Cage is a joke, and the song itself pretty silly.
The new album: I barely get through the first two songs.

Meat Puppets, Screaming Trees, Melvins, even Mudhoney: those are some underrated bands.
