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.
