Chrome native sync vs cross-profile bookmark sync

They are not competitors

Chrome's built-in sync is excellent at what it was built for: making one profile identical on every device where its Google account is signed in. It covers bookmarks, history, passwords, extensions, settings and open tabs — far more than any extension should. Braid Sync covers one thing Chrome sync deliberately does not: moving selected items between profiles. Turning one on is not a reason to turn the other off.

Coverage compared

When Chrome sync is all you need

• You use a single profile on every machine.
• Everything you bookmark belongs to the same account.
• You want passwords and history to follow you — Braid Sync never carries those.

When you need cross-profile sync

• You keep separate work, personal or client profiles and re-bookmark the same links in each.
• You research in one profile and execute in another.
• You use both Chrome and Edge and want one shared reference set.
• You want to share bookmarks without sharing an account.

Other approaches, fairly stated

Exporting and importing bookmark HTML works and costs nothing, but it is a one-off copy with no deletion handling — the copies drift within a week. Signing two profiles into one Google account shares everything, which defeats the reason you separated them. A standalone bookmark manager gives you a good library but lives outside the browser's own bookmark bar, so muscle memory suffers. Each is a legitimate choice; the guide walks through all of them.
