// EDITOR'S TAKE

Seafile wins on the thing that matters most, fast and reliable block-level sync, with optional end-to-end encrypted libraries. Nextcloud syncs less crisply but brings the sharing, commenting and app ecosystem Dropbox users expect, while Spacedrive indexes drives you already own instead of hosting storage for you.
