The reasons to switch is mainly for the massive speed increase (2-4x for
jpeg compress/decompression). It is something that I would have
considered earlier, but I did not think a rebuild was worth it. But now
they support the version 8 API and no rebuild is necessary, it is a good
time to switch.
As the package maintainer, the libjpeg-turbo development is also much
easier to follow. It has mailing lists, a bug tracker, a SVN repo, etc.
libjpeg basically has an email address and that is it... We have had
a bug in libjpeg before that I had to wait for upstream to make a new
release to fix (which admittedly was done quite quickly), rather than
just grabbing the patch from SVN.
