Yubikey vs phone Authenticator

Just would like to get opinion on using Yubikey vs phone Authenticator as 2FA for applications like GMail login etc.

I think both are regards as secure, as of today, right?

With Yubikey, there is a situation that if it is lost, I will loss access to the service. But with phone Authenticator, likely, I'll be able to use another phone to recover access on the Authenticator, right?
