Yeah - it really depends.
If I remember correctly - I was playing with bzip2 and gzip for man
pages on my lfs system, and for the man pages - gzip was both faster
decompression (when man wanted to read them) and smaller - in general,
but for info pages - bzip2 saved a LOT of space - I think the more data
you have (text files anyway), the better compression you get out of
bzip2.

I pretty much just use gzip though for everything - the extra space
isn't that much and gzip is pretty standard everywhere.
