First, the two schemes presented, showing common emitter configurations. The name of this configuration, because the emitter terminal is shared by the input circuit and the output circuit.
The main difference between the two, is polarization. While the first uses a resistor divider to set the base current at rest, the second uses the resistive circuit, associated to the collector.
In principle, by using the resistor divider, can select resistance values that give good bias stability against variations own transistor parameters.
As for the application of both circuits in RF, I think it's more a matter of working with class C amplifiers and tuned output circuits. Perhaps you have generated some confusion the impedance characteristics of the three basic configurations:
- A common-base amplifier is a good voltage amplifier with a high output impedance.
- A common collector amplifier is a good current amplifier with a low output impedance.
There is a mixed configuration, called "cascode" which is widely used in RF circuits, but as far as I know, should be implemented with two transistors.
