Well, lets deal with facts on your hypothetical QRO station:
Transmit power 500 watts S-9 +10 db
50 watts S-9 (+ 10 db over 9)
12.5watts S-8
3.1 watts S-7
You lose 1 S-Unit each time you're reducing power by 1/4.
One S-unit consists of 6db increase or decrease in received signal
strength. Transmit power must be increased FOUR TIMES to achieve a
signal strength increase of one S-Unit!
A QRP signal is mighty respectable at S-7 on anyone's receiver.
I will still prefer my K1.

All the rationalizations and anecdotal experiences aside,
there is no escape from the physical reality that a 100 watt
station will be 13 dB stronger than the same station running QRP 5
watts.
Whether or not this 13 Db is crucial depends upon propagation
conditions and noise and QRM levels at the receiving end.
