In my opinion, this is, from one side, depend on application and signal detection method. If our detector - voltage comparator, then we are interested in small rms value, but if our detector works in spectral domain (after FFT), then - in low noise floor.
But, from another side when we use ADC, problem of folding exists and rms value of noise is very important.
In almost all systems main parameter is SNR (not SFDR), so rms noise value more important parameter.
