Quick take
Among these two, Proton Drive wins if you do not want the storage company reading files. Google Drive wins if live collaboration, search, and a 15 GB shared free pool matter more. 200 GB pricing is close enough that trust model should decide. This page does not rank Dropbox, iCloud, or anyone else.
Why this pairing exists — and why it is not a trophy
People search 'Proton vs Google Drive' because they already live in Gmail and they heard Proton encrypts. Those are different jobs. Google Drive is a collaboration surface attached to an identity you probably use all day. Proton Drive is a zero-access cloud attached to a privacy company. Scores on this page are for these two products, in this story. They are not GUIDEORA's ranking of every cloud.
From the record
If you need twelve people commenting in a Doc, encryption theater will not make Proton into Google. If you need the host not to read the Doc, Google's convenience will not make it Proton.

Collaboration and convenience
Who can read the files
Proton documents Drive as end-to-end encrypted on the device, including names. Google Drive for ordinary consumer accounts encrypts in Google's infrastructure; Google can provide files under legal process and can power features that need content. Google Workspace client-side encryption exists for organizations that turn it on — it is not the default consumer Drive your uncle uses.

Free tiers and the 200 GB bracket
Google's free 15 GB is shared with Gmail and Photos, so it fills faster than the number suggests. Proton Free is 5 GB dedicated to Drive/Photos/Docs in Proton's listing. At 200 GB, public round-ups in 2026 often put Google One near $2.99/mo and Proton Drive Plus near $3.99/mo billed annually. Close enough that keys, not 80 cents, should decide. Confirm checkout; GUIDEORA does not freeze vendor prices.
Where each tends to win in this pair (editorial)
Editors, Photos, and sharing
Google Docs is the default language of group work. Proton Docs and Sheets are encrypted and lighter. Google Photos is a product; Proton Photos is a private backup. Sharing on both can use links; Proton's pitch is password and expiry on an E2E file. Google's pitch is comments, suggest-mode, and add-ons.
