What's your favorite personal cloud solution?

I'm considering switching from a selfhosted Nextcloud AIO to a managed cloud provider (e.g. MS OneDrive) so I don't have to care about backups, security, etc.. However I like the flexibility I get from self-hosting.

Can you recommend any cloud providers for the typical Linux user / web developer?

Recently I've switched from the UNIX pass password manager to Bitwarden and I'm very happy with it. So I'm looking for something similar among the cloud providers.
