I found OneDrive had significant performance and reliability issues a few years ago, but I’m happy with its performance & reliability these days. My only significant issue is it doesn’t handle very long file paths. If it wasn’t for this file path issue I’d transfer over all my general file syncing needs from Dropbox (which I’ve used as a paid user for over 10 years) to OneDrive.
Dropbox is excellent (I haven’t had a single issue in over 10 years) but if you’re a Microsoft Office user Microsoft 365 pricing is unbeatable especially if a family plan is useful.
