No because hartley uses inductors which are bulky and economically not feasible to obtain tuning inductors as compared to colpitt's which uses capacitors which are relatively very cheap and small.

Where a colpitts oscillator is used?
the Colpitts oscillator , named after the inventor of the circuit , is characterised by the use of Two Capacitors in series which are then connected in parallel across the inductor of the resonant circuit for obtaining the required frequency. The junction of the two capacitors is used for the positive feedback used for generating the oscillations. This circuit is used for High frequency oscillators , mainly due to ease of obtaining required ratio of the two capacitor values as per the circuit design. Also the two capacitors in series reduces their total equivalent value , which is not a problem as in HF circuits as the values and size is comparatively low. For information , a corresponding Low frequency circuit is called a Hartley oscillator , also named after its inventor. This uses a tapped inductor & one capacitor for the resonant circuit, since it is more easier to fabricate large value tapped inductors , than to use two bulky ( since the value of capacitors in series is reduced ) capacitors necessary for the equivalent Colpitts oscillator.
Why piezo crystal oscillator used?
Piezo-electric quartz crystals are used to define the frequency in a crystal-controlled oscillator. Quartz is a hard material that tends to oscillate mechanically at a high frequency (up to about 20 MHz) when maintained by the maintaining amplifier. The signal produced is far more stable and predictable than an L-C oscillator, especially when the crystal is placed in a dedicated oven with a controlled temperature.
How op amp works as oscillator?
oscillator needs positive feedback in order to produce the undamped oscillations .This is done with help of he amplifier circuit.The oscillations are produced by the tank circuit cosisting of inductor and capacitor.The output of this tank circuit is fedback to the transistor which amplifies it and give back to the tank circuit input.If the gain of the circuit consisting of tank circuit and amplifier is more than one and the feedback given to tank circuit is in phase then we get undamped scillations as the output.
Is polypropylene better than polystyrene?
That depends on how you define "better" and what you're using it for.
Are ductless air conditioners better than ones with ducts?
Ductless air conditioners are not better than ones with ducts. The reason why ductless air conditioners are not better than ones with ducts is that they don't remove the hot air as well.
What are the advantages of a Hartley oscillator?
advantages over what? Colpitts? Mostly the fact that it does not require a choke. A Hartley is more harmonic-rich than a Colpitts, so the main reason it is used lies in its (relative) ease of construction.
Is hartley oscillator is better than colpitt oscillator?
Colpitt oscillator is better than hartley because colpitt produces less phase noise and uses capacitor instead of inductor as used in hartley oscillator which means that area is also saved.
What are the advantages of oscillator?

Why PLL better than VCO?
A PLL is different than a VCO. Each has its own use. Actually a PLL (Phase Locked Loop) contains a VCO (Voltage controlled oscillator). A VCO is an oscillator whose frequency is related to an input voltage. You can use it when you need a varying frequency that is controlled by a varying voltage. But it is not great at outputting a consistant exact voltage because it is very sensitive to its environment (e.g. temperature). A PLL will "lock" its output frequency to some input frequency. So it can oscillate at a frequency that is controlled by an input oscillator. Not too useful if the output frequency is the same as the input. But the output frequency can be divided before it is compared to the input. This allows the output frequency to be higher (some multiple of) the input frequency. Once a PLL is "locked on" to an input frequency it can be very stable.
Am i better than you?
You are the worst person ever. You are better than no one. And no one is better than the best. So you must be better than the best. But the best is better than the worst. So it is impossible to tell if you're better than me. No wait. I change my answer to "No, I'm better than you."
