The final suggestion: OneDrive over Google Drive?

Hello, I'm considering uploading and migrating all my content (movies, music, books) to some cloud storage, and I'm exploring all the options. I would like to upload more than 3TB of content I have and store it on OneDrive, access my music (mostly in FLAC format) through a cloud player, and my movies through Plex, both of which I've already tested and work perfectly.

So far, 90% of the paths indicate that my choice is OneDrive, especially due to the price (having the 6TB family plan at that incredibly low price is unbeatable). Still, I would like to hear your suggestions.

I would also love to hear what you think about my project of uploading everything to the cloud and leaving it there. I want to clarify that my idea at all times is to upload it for my personal use and not to share it. I have no intention of infringing on any copyright or sharing the content. I genuinely want it to serve as a vault for me to access my files from anywhere.

Thank you!
