Another question about browsers

So....Microsoft Edge wants me to sign in using my outlook email (to sync), and it won't allow me to use the adblocker, Ublock Origin, unless I'm signed in....this kind of defeats the efforts to get privacy.

Which will give me more privacy? To sign in and use the adblocker, or to use the browser without being synced (but I've got VPN either way)? I'm not even going anywhere questionable. 😆

Is Google Chrome better? Is it the safest to use with gmail and Ublock Orgin? Gmail has a new protection feature, but I don't fully understand what it does...

Any help would be welcome.
