Among Colpitts and Hartley oscillator, which has high power RF out? And better?

Look at this Tx too www.next.gr/uploads/262-864a321e51.gif
-Which oscillator used here? Hope it has high output than normal.
-How simple 494 transistor will not burn at 12v?
-AND main question is at the title please

The oscillator is a Colpitts, followed by a Class C RF Amplifier.

As to your main question: Which has a higher output? Ford or Chevrolet.
Better? Ford or Chevrolet.

Implication: some people like Fords, others like Chevs.
