[MLB-WIRELESS] Best Radio and Antenna Gain Configuration?

I have a question in regards to the best radio and antenna gain configuration.

Which configuration will give the best signal quality:

1) A high powered radio (200 mW) (23 dBm) with a 13 dBi Antenna, OR
2) A low powered radio (30 mW) (15 dBm) with a 20 dBi Antenna.

As an analogy, in audio systems the signal takes the following path:

* Input Socket
* Input Preamplifier
* Equalization
* Output Fader

Having a lower input gain will allow for a cleaner signal to be carried to 
the output fader. Increasing the input gain will overload the preamplifier 
and send distorted signal to the output stage.

Any comments would be appreciated.
