3.1 upgrade or install?

["J. Scott Edwards" <sedwards@xmission.com>]

After reading the "List intolerance VS advocacy" thread and

I'm a little nervous about asking this question, but since

http://www.openbsd.org/faq/upgrade-minifaq.html#1.9

didn't really answer my question, I guess I'll give it a go:

I just received my 3.1 CD and would like to install it as soon as I have
time.  When I did the 2.9 to 3.0 upgrade, I backed up 2.9 and did a clean
install, which worked very well.

<suck up>And I should say that OBSD has one of the easiest and most
straight forward installs of any OS I've ever installed which includes
Win3.1-2000, Mac 7-X, 31 flavors of Linux, FreeBSD, et. al.</suck up>

So I was planning to do the same with this CD, just back up 3.0 and then
do a clean install and rebuild the kernel for netatalk support.  So my
question is would it be better / easier to do an upgrade instead?

Thanks

P.S. I really was impressed by how easy it was to install OBSD.  I just
followed the directions on the CD insert and voila I was up and running.
