Up to your last imagery, you see what exactly's supposed to be seen.
The difference between guns however, is a lot less than what it was.
Due to that, the "bad" guns as you call them, can easily topple the good guns dependent upon the player using them. However, such an effect won't be fully utilized until players absolutely adjust and begin to actually gain skill.

Basically: A gun is as good as its user is the change. However, players can't be made good users overnight. So this update is an effect to be rendered in a timely fashion. Those who realize the effect immediately, are the players who already were at that level of "good".

Sounds very immaterial, but give it a thought. =].
