Default Which Crystal Oscillator circuit has lowest jitter

....it's Colpitts, Hartley, Clapp,Butler and Pierce!
go with Butler since it has the crystal inserted between points of low
impedance, it actually boosts the Q of the crystal above the unloaded
Q. this Q is ths single most important source of jitter and attendant
phase noise.

Which configuration with JFET or BJT would yield the highest performance
and least jitter?
