iCloudを選ぶべき人: Apple全投入なら考えずに使えるバックアップとSyncが欲しいAppleユーザー

本当の違い
Both offer free tiers, so the real question is what you get when you start paying.
iCloud stands out with Seamless sync across iPhone, iPad, and Mac and iCloud Drive with Finder and Files app integration. Sync.com counters with End-to-end encryption by default and Zero-knowledge privacy.
iCloud's Achilles heel: terrible experience on windows and android — and 5gb free in 2026 is embarrassingly stingy. Sync.com's: no native document editing — you have to download files, edit locally, and re-sync every time. Pick whichever weakness you can live with.
結論
If you value seamless sync across iphone, ipad, and mac and apple全投入なら考えずに使えるバックアップとsyncが欲しいappleユーザー, go with iCloud. If 追加料金なしでデフォルトのzero-knowledge encryptionが欲しいプライバシー第一のチーム matters more, Sync.com is your pick. Neither is a bad choice — but one will fit your workflow better.
