Again, thanks to all for the feedback. This has been a good discussion. I like to keep my system as clean as possible but also want to balance that with not going overboard. It's running fine right now so will just burn the ISO for backup for now.
In my opinion Microsoft have improved the upgrade process and made it a lot more efficient in Windows 10 than it was in previous versions. I would recommend upgrading your system for speed but if you prefer to do a clean install it's up to you.
I've already done the upgrade, it was just a question if I would blow it all up and do a clean install over the holidays. I'm going to leave it alone for now.
