Definitely up there.
The Wedding Present - Seamonsters (1991) completely obliterated everything both the US and UK rock scenes were producing simultaneously, I think that's hugely significant.
Tindersticks have been a consistently good/brilliant act since 1993, though it's tough to pinpoint one album. The debut is remarkably assured with some of their best songs, but runs a little long to be a classic.
Pulp were the best of the mainstream Britpop wave by a mile, I'll go with Different Class because it was their high-point career wise, though His 'n' Hers remains underrated.
I agree that the RATM debut would have to make the list, never bettered within a field it defined.
