This is probably a gross generalization, but it seems to me that a lot of the people that feel they need tons of extra power perform with a considerable amount of distortion. It also seems that the times I have been more successful in standing out in the mix or sounding good on tape come from using less of that. Mind you, I said "less", not "none".
As a convert to relatively 'clean' power myself, I am going to give you a really cliche sort of spiel: When you listen to a guitar, you are listening to a musical instrument. That being said, the sounds coming out of that instrument have nuances and overtones that are fundamental in giving that particular instrument its tonal charactersitics, timbre, and 'voice'...and ultimately they are what will distinguish it from other 'sounds' coming from other instruments in a band setting. Tons of distortion hides a lot - it amplifies all of those tonal characteristics to the point at which none are louder than any other, and thereby removes a lot of the "character" from a tone. And, when you stick that into a band situation, you will be "fighting for frequencies" with other band members. Once your guitar is loud enough, the crash cymbal will disappear. All of a sudden your drummer is banging harder and you'll have to keep turning knobs.
Personally, I tend to run a smaller tube amp so hot it breaks up at the power stages and get a better, seemingly louder (i.e. MORE AUDIBLE) tone - even compared to a 100-watt head and a 4x12" cabinet with some sloppy four-transistor-gain-stage distortion pedal.
This sort of volume is what will compete with your drummer, not all the high-frequency hiss of a saturated guitar tone. And, on top of that, I at least find it really refreshing to have a screaming pinch harmonic and realize it's not audible because of a stomp box, but because my amp is just that damn loud (and, in fact, STILL is not putting out the decibel level of a monster amp and a "Cheese Metal" foot pedal).
