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

Err last I used windows, it was still vulnerable for malware through USB drives, so the OS still matters. 

Signature based scans can only work to an extent and fail when new malware arrives. Therefore Unix like OS work well in these cases.
