Best 13mm p&b

Okay so I know a decent amount about a p pump and how everything works I also know there are 3 different types of 13mm p&b offered by bosch my question is which one is the best. Here's a pic of them they seem to look like they would all fuel different.

The higher the bottom of the cut is, the sooner the port is closed off and injection can begin. Depending on where the barrels are set it looks like the middle ones would start injection later than the other two.

I worded that wrong. The area in between the angled cut and the top of the plunger is where the actual injection event is made. So the greater the distance between the top of the plunger to the top of the cut the more fuel will be injected.

They are the same plunger, just made by three different manufacturers.

I would think that the one on the far right would have the highest volume of fuel but the middle one would have a quicker fill rate and the one to the left maybe the lest favorable correct me if I'm wrong??

Can't say for sure your wrong. But the top of the plunger to the top of the helix looks to be the same on all 3 from the picture, which I believe is what matters. Heck maybe I'm wrong. I would take what smokem said for gospel and consider the question answered correctly...

Considering the plunger on the left is mine, and the fact that I know who took that picture, you may just take what I say as the truth.
