Less flavor, maybe, if you water is extremely cold, Less clouds, hell no.
Diffusers break up the large bubbles in the water into smaller ones, the surface area of a smaller bubble has a chance to cool down much faster than a large bubble, giving you a thicker smoke.
Diffusers will increase resistance, increase cloud density, reduce noise, and possibly reduce flavor depending on what you're smoking and the temperature of the water.
