For me, it is deff QUALITY, over quantity.
Just look at some of the major guitar players.
Unless you are in Radiohead or that scruffy looking bloke in RHCP, or in a worship band (ever notice how many pedals they have ?), why do you need 10-25 pedals on your board. Or even one pedal that can do 10 diff types of dirt.
Unless you are in a cover band, playing other peoples stuff, you only need YOUR tone, and i cant remember the last time i heard a well known guitarist with 5-10, or even 12 diff dirt tones.
GOD, ermmmm, Jimmy Page has one dirt tone, Slash has one dirt tone, Jack White has one and a half (grity transparent tone and a Big Muff tone), and, and, and.
Look how many pedals (total) they have :
Slash has maybe 3.
Jack White has 4 (and that incl. a tuner)
Garry Moore (R.I.P.) hardly had any.
Rory Galhagar had 1 (most of the time)
Angus & Malcolm has zero.
Liz Buckingham has non (most of the time)

Right now, i have on my board :
