Ah yes.  They're using the same compression algorithm as 7zip, but they're
in-line-filterable, and behave just like a normal "gzip" command etc.

AKA, there is never any reason to use bzip2.  Using lzma --fast is much
faster, and better compression than bzip2.  It's superior in every way.

lzma is not as fast as either gzip --fast or lzop, so those guys still win
for fast compression.  But lzma dramatically pounds them into the ground, as
far as overall performance is concerned ... compression per cpu cycle, and
total compression.
