It's been many years since either was near a calibration lab. One is 30 ppb fast, the other is 75 ppb fast. (I might have the sign backwards.) One swings roughly 0.15 ppb over 10F. -- These are my opinions. I hate spam.

Hi If your time base is doing < 5 ppb per year, that is an unusual 10811. I suspect it does not spend a lot of time powered off.
