Choose Bookmark Nav if

You want to keep using Chrome bookmarks instead of moving your collection into another service.
You care most about fast retrieval, folder context, cleanup, and new tab access.
You prefer a local-first extension with no account, no analytics, and no bookmark upload.

Choose Raindrop.io if

You want a dedicated bookmark service available across many platforms and devices.
You want collections, richer item metadata, apps, and cross-browser access.
You are intentionally replacing native browser bookmarks with a separate bookmark system.

Bottom line

Bookmark Nav is not trying to be a cloud bookmark service. It is a practical upgrade for the Chrome bookmark tree you already have. Raindrop.io is better if you want a larger cross-device bookmark system.
