As a point, the setup of the brake will have much more to do than the pads themselves. Pads can perform and sound so different with different frames/rims/boosters/grinds etc etc.
I prefer a brake as quiet as possible (used to love it as loud as possible back in the day though!), as you probably agree it just makes riding seem a bit smoother & refined!
Stiffer frames and boosters will help here, as the flex and vibration (read: noise) are minimised. Slightly less sharp grinds will also reduce the vibrations, whilst the lack of bite/grab can be compensated for with a stiffer set up and even a longer lever blade giving you more power and control over the brake, effectively making it more modular but still with that definitive lock!
On the contrary, harsh, sharp grinds and less stiff setups are more likely to have higher bite and noise, with the expense of a bit of holding power, but have the benefit of more confidence in wet weather conditions.
Hope this helps,
