How do reflex klystron low-power microwave RF signal generators compare to modern solid state ones in terms of frequency precision and stability?

Did you get a multiple choice option on your homework

As compared to what, an LC oscillator? DDS synthesizer? Hydrogen maser? Cesium fountain atomic clock? Should the signal source be: variable frequency, high accuracy, high purity, low drift, etc.?
The nice feature of a reflex klystron is, it's a VCO (voltage controlled oscillator) over a small range, usually defined by the resonant chamber's bandwidth. The inherent stability is probably low (defined by the resonator's Q), but it could easily be mixed with a more accurate source and PLLed to similar stability.

Driven by... quartz oscillator, precision timing reference, WWV or GPS? (Which are tied to NIST's atomic clock.) I would expect a klystron to be comparable to an LC tuned VCO, putting it a couple orders of magnitude below a plain quartz tuned DDS (and a few orders of magnitude further below anything disciplined by the atomic clock, give or take jitter).
