Welcome to CDF!
I would use either - but the key being that I would make another 2 copies of each, on known good media.
I have three sets of everything I own.
One set for “everyday use” - which I store on whatever media is lying around at the time.
Then I burn two additional sets - one set on Taiyo Yuden media, the other set on Verbatim media. These last two are my archival backups.
But that’s just my personal preference - I’ve had to restore from one of the backups on a couple of occasions, and I’m glad I made them.
