I think Yubikey and its ilk certainly increase the security over typical 2FA but there are downsides but this isn't really the ideal place to discuss this, simply because this thread isn't about the Pros and Cons of 2FA or Yubikeys but rather returning to 1Password after switching to the competition.Get a Yubikey
I listed pros and cons of 1PW and BW and I really like BW but I feel 1PW offers a bit more. I also highlighted that when I log int BW I'm being told that I have to switch to 2FA. I mentioned that before, I don't like being forced to do that and generally as I stated I would prefer a more seamless less intrusive solution, a la 1Password
To me, security is a balancing act of convenience and complexity and imo 1PW's implementation is elegant imo
