I don't feel It makes them better, but back when I was still making them up that way, I had received feedback from people that felt It made them more consistent, therefore It could be perceived that way by some. I have heard that unpressed starts out softer feeling, but hardens over time, as with many type of tips. This I already knew, but that was the feedback that I was getting from some customers.
Some people didn't like certain types of tips because of that change, as where others wanted that feel from the start, so milk duds, pressing, and what not helped provide that for them. I use to make milk duds from about 3 different type of tips, but now days I just recommend spending a little more for a more consistent tip in their preferred hardness level, but even some of the tips that cost more act in a similar way, and hardness changes as they are compressed from normal play..
