Mike, Luciano is correct. The HP 5065A beats all the others easily.
It is not configured however to be disciplined although it can be modified. It's main claim to fame is the excellent short term stability. If all you are after is a long term accuracy standard then any of the others would work. There has been a lot of work done with disciplining the FE-5680 and also temperature controlling its baseplate. Results are very good!
