"Highest performance"? Is that output amplitude? Or minimum startup
time? Or startup reliability? Or lowest power requirement? Or what?

Jitter, that's a little easier to define but it's usually not the most
relevant parameter in radio. It is related to sideband and phase noise
and in fact cannot be completely decoupled from either.

Its not for a radio. I want to minimize the cycle to cycle variations in
timing and it should be simple enough to make with 1 or 2 transitors. So
not looking for NASA spec stuff, just reliable so it starts every time.
