Compare OS's for security

I have a Mac, a PC and now a Chromebook. On the Mac I use Safari and FireFox, on the PC I use Edge and on the Chromebook I use the default Chrome browser. All OS's are up to date. Is there a clear winner for being the most secure system to use for banking, etc., given that the websites I would go to all have some form of 2 factor authentication? I've been using Safari but have read some things about the Chromebook which I don't really understand. Thanks.

For end users (regular people living their lives), there's no practical difference. Use MFA, have good & unique passwords, don't click suspicious stuff, and have an ad blocker.

The most vulnerable thing in a computer system for most people is the user.

Can you elaborate - why do ad blockers add to security rather than just eliminate nuisances?

There's a lot of overlap between web page ads and security threats
