Try the upgrade first and if that has problems then go for the clean
install.
Before doing the upgrade read former MVP Gary Woodruff's article on
upgrading to XP at
http://aumha.org/win5/a/xpupgrad.htm
And if you do decide on the clean install option then you should use
the Files and Settings transfer wizard from XP to save your WindowsMe
data files and configuration settings to another hard drive partition,
a network drive, or a backup device (e.g. CDRW). Gary also has an
article on using FASTW which is at
http://www.aumha.org/win5/a/fast.htm
p.s. I personally have upgraded from WindowsMe to XP numerous times
without problems as I was running WindowsMe during the beta testing of
XP and I installed each new beta version as an upgrade of a copy of my
WindowsMe partition. My current system is XP Pro upgraded from XP
Home upgraded from WindowsMe (upgraded from 98SE upgraded from 98
upgraded from 95B upgraded from 95 upgraded from 3.11). It works just
fine with no errors and takes less than a minute to boot.
Good luck
