hartley osc
It is not true that Colpitts topology has any inherent advantage over Hartley, phase noise or whatever.
Each has a resonant circuit that is connected in the same place. The only difference is that the tap on the resonant circuit is implemented with the capacitors in the Colpitts and an inductor tap in Hartley. One outcome of the inductor tap is that the Hartley has some tendency to have parasitic resonances as the inductor is divided by the tap into two parts, and the mutual inductance between them has a final value. On the other side the Hartley has less capacitors.
I have used in the past the Hartley discrete topology many times with excellent results and performance.
