quattro vs. Syncro??

[Iain Mannix <mannix@privateI.com>]

What exactly are the differences between the quattro and Syncro systems?
More specifically, the 4kq and VW qsw - I just saw something in the Audi
newsgroup claiming that "old Syncro" is/was not as desirable for high
performance driving as quattro - any insights?  I have been told many
different things - some say it is the same, some say the rear suspension is
different but otherwise the same, and somewhere down the line I got the
idea that they were somehow different.  Insights?  Thanks!
