Subject: Question about Group Heads
 

I noticed that the Group Heads on machines either use a flat disk or a screen mesh for water dispersion. May I ask what are the differences between the two? Is one suppose to be better than the other?

Or some use both, like my E61, it has a disc under the screen. The whole goal is to get even water flow over the puck so that the whole bed of coffee is covered evenly and at the same time.
