OneDrive is sooo broken underneath. It should be a no-brainer to pick it, a sensible default, like Edge, but Microsoft always manages to fuck it up worse somehow.

It either just manages to work for you (count your blessings) or you'll have some cursed bit set in some forgotten Microsoft table somewhere that means you'll be doomed to a horrible experience forever without a clear cause. Infinitely (not) syncing folders, disappearing files, cryptic or vague error messages. Even on brand-new machines.
