Can't match the Sex Pistols pumping out ONE album, imploding, and then being remembered as the definitive punk rock band. Kurt even named Nevermind after that album.
Sixteen Stone by Bush sounds a lot like Nirvana in some aspects but it's still a good listen. The one problem is that it's all very same-ish.
Siamese Dream by the Smash Pumpkins is a mix of alt rock, progressive rock, and grunge but it is often pointed to as one of the better grunge albums. You've got bangers like Cherub Rock, Soma, and Mayonaise. Mellon Collie and the Infinite Sadness is also a really good album but it's a bit less grunge than the other album. It has some great grunge songs like Zero and Bullet with Butterfly Wings but then you got some serious progressive rock with something like Tonight, Tonight and 1979.
