JBIG2 might be the best compression for bitmap images, but you probably never want to use its lossy mode for text images[0] The fact that a single difference in a configuration bit (lossy/non-lossy) can introduce subtle and easy-to-miss errors (to the point that this went unnoticed by Xerox QA and thousands of their customers!) is an indication to me that while JBIG2 might be superior in terms of the compression it offers, it's not a solution I would use without very serious consideration and deliberation. Just to make this more clear: if you borked the compression setting on jpeg, you get smeared images. If you bork the lossy/nonlossy flag on JBIG2, you get images that look great but may have a random letter or digit swapped for another.
