Reinstall W10 or 'Custom'?

I'm installing W10 (Pro 64b) but have the W10 HDD from old system in my new build. Thinking I'd get option to overwrite (I have a backup). I think a "fresh install" is best, but it's asking if I want to 'Upgrade' or 'Custom' install. Says Upgrade will copy my files, appls, etc.

It would be nice to just switch the key and anything w/ recognizes the new hardware. It can't act like an "Upgrade install" from W7 or W8. Only Windows on this HDD has been 10. New mobo, cpu and ram. If it overwrites W10 files it sounds like same files written as during a fresh install.

What are any downsides to choosing 'Upgrade'? Also, do you think I'll get to choose between build 1903 and 1909, released today?

Thanks for any input,

I seem to always read (mostly) that a clean install is safest.
I don't want to worry about "what ifs" so I do it the hard way and reinstall programs...(PITA tho)

Since you already have Win10 installed, an upgrade will not be an issue. A new install will not get you much.
