I don't think they sound too different between albums.. just different sides of the same coin... obviously, they have some more rocky stuff as of late, but it still fits in pretty well with their dronier, noisier albums. Honestly, it's comparable to something like.. yeah.. the Melvins or something. They can do some different things (and the Melvins have done a lot weirder things probably), but they're still true to their original sound usually.
Actually, "Smile" might be the weirdest thing Boris has done thus far. But I like it a lot.
