No web browser offers a good out of the box experience.
I feel like there is no web browser with a sane default configuration that I can recommend to other people. All browsers are preconfigured in a way that harms the privacy of their users or include services that no one wants such as Pocket and BAT.
Here are my problems with some popular browsers.
Mozilla Firefox: Pocket integration, no ad-blocking without extensions.
Brave: Everything related to crypto. Also its start page is horrible.
Chromium: No ad-blocking without extensions and soon Manifest v3 will cripple all content blockers.
Now, these suboptimal defaults wouldn't be such a big problem if the configuration files were easy to backup and restore and respected the XDG base directory specification.
Yep, also they don't integrate Pocket in the browser, they just have a built-in email client, note-taking software, RSS reader, calendar bloat. Also, Vivaldi is based on chromium (as such subsribed to all Google's bullshit), and uses Chrome extension store.
Honestly, OP, just stick to Librewolf, it's privacy-respecting and actually open-source, pocket's disabled, UBo's preinstalled.

You literally get a button when you first install it asking whether you want these things. One click and they're disabled. Also OP post is about privacy not bloat and these features will only improve your privacy over using some webmail.

All google stuff is either removed or toggleable from settings.

What's wrong with that? It's a good deal larger than mozilla's
OP is concerned about Pocket integration too, so I assumed they may not like it.

Does their built-in mail support any good encryption? The last time I used Vivaldi a mail feature wasn't really that private. Also, using dedicated email client like claws or mutt is even better from privacy perspective.

They can't remove Manifest V3 though.

Yes, and it's under Google's control. And, again when I used it last time, you need to enable some google stuff to install extensions from the store.
Basically, you don't want everything be dependant on a central authority - this is a single point of failure. If there's a big security vulnerability in your web browser, but you use a standalone mail client, your mails are most probably safe.
This also adds up to built-in adblocker - who knows if Vivaldi devs will ever go evil and sneak in exceptions in their adblocker? Or if they will sell their web browser, just like their CEO done so with his previous browser, Opera.
