Hi !

Any of those oscillators is OK if resonance circuit Q is kept high and
oscillation power in average low level.
High Q will guarantee easy and fast starting every time
Average low level keeps components cool and cycle to cycle variations
are reduced
Third important question is loading the oscillator.

Good info thanks. What are other crystal series oscillators besides Butler
type?

One type not mentioned is the Franklyn, which IIRC is a cross coupled
multivibrator with one feedback path through the rock.
