The reinstall is cleaner, however, it can be more work.  If you have 
several users, you will need to preserve your /etc/passwd and /etc/shadow
entries for the system.  If you are using samba as a PDC, you will need to
hang on to some of the files from /etc/samba.  Your web server configuration
may also have to be redone or at least redirected to the partition where
it the configuration files are located.  Any automounter config files will need to
be fixed up.  I am sure I am not remembering everything from my list.

My suggestion is to take a tar of /etc and put it somewhere safe.  I have also
seen it recommended to save the output from rpm -qa.  Then try the upgrade.
If something goes seriously wrong, you can do the clean install and you
can dig the information you need out of the saved /etc.

It kind of depends upon how much setup work you have done that would have
to be redone.  If this is a simple desktop running no special services,
then the upgrade does not buy you much.  

One more thing, before a reinstall check to make sure you did not leave
anything important in /root (root's home directory).
