People at the level Stickman refers to want what they want. They usually aren't as invested as us online gun guys are with Brand X, Y, or Z. They want a capability, they want a performance, and they usually get it tailored to their specific and sometimes individual needs and desires.

It's like a Pro Football player wanted these cleats, these pads, etc etc. Why? Because he wants them to perform at a very very high level. So he gets it. Not because your preferred brand sucks donkey balls, but because he wants what he wants.
