Trezor is really cool, bas a two-factor authentication key -  is not as convenient as Yubikey. Yubikey is small and very dense to the touch, there really is nothing to break in it, unless it comes under the influence of very high temperatures.

He is not afraid of water, falls even from a great height are not afraid of him either. What can not be said about the Trezor.

If he gets caught in heavy rain or falls into the water, then everything will be over with Trezor.

It is also not so reliable because it has a rather thin plastic case, so it must be stored very carefully. And certainly on long trips, I would rather take Yubikey with me than Trezor.
