The reason Stellar and Ma Belle are B-sides are because they didn't fit in the mood/feeling/whatever of the album, not because they weren't good enough. Otherwise I don't think they would bother playing them live (Okay, Ma Belle hasn't been played live, but the others have. And I don't think they would of bothered recording Ma Belle if they didn't like it, otherwise it would of stayed at demo stage or something.)
I'll agree that the drums are great, but come on, the whole song can't rely on that. IMO the rest of the song is bland, and merely an attempt at doing an epic song for the sake of having a long song on the album. I think Stellar, at 6:20-something is long enough to be epic.
The fact that the drums were recorded in one take means that

is a really good and talented drummer. It doesn't mean the song is good because of it.
Silverfuck or Geek U.S.A. or Fuck you or Lucky 13 are some damn epic drum songs.
Sorry if I come off as kind of hostile saying all that..
EDIT: Don't forget Superchrist! A bit of a lame song, but I think it's much more Pumpkins sounding than US.
