> From your experience, which password manager is the good choice? And what syncing, additional security layers (like key files, YubiKey...) could be used to gain maximum protection of the sensitive information?
Every time someone asks 'which one has the best security', the first question you need to ask is - what's your threat model? Because that will impact what your requirements are. Personally, my threat model includes people physically getting hold of my laptop or phone, people using my computer when I'm not around, keylogging/malware, or websites having their passwords breached. It doesn't include the NSA, nation-state adversaries, spear-phishing attacks.
This impacts which software I use, how I've set it up, and my use cases.
