The sound is much more solid because of having more mass. No plinky thin-, annoying- and unwanted overtones, but a more pronounced loud-, clear- and bright tone with lots of bottom-end. Your guitar never sounded so full and you never played fast and picked accurately that easy. Easy to hold avoiding the need to grip too firmly. The material also helps avoiding chipped edges, and ensuring months, if not years, of uninhibited, uninterrupted playability.
 
The beveled edges allow the pick to glide on and off the strings effortlessly making it easier to play.
