 I find that upgrades work very well for workstations. My workstation has a few 
services running, apache, samba, nfs, multi-head xorg file, multiple hard drives 
(fstab) I like that I don't have to start over configuring stuff to get back to 
where I was. It might depend on how complicated your setup us.

I do like separate partitions/hd for /home, /usr/local & /pub/mirrors. A fresh 
would not be a complete disaster.

In my experience upgrades have gone well as long as I read the release note, I 
also following this list for heads up on issues.
