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.
