This depends on how you want to approach the issue of dropping it on concrete. I have an MBUS, but use the DD fixed rear on my carbine.
My impression is that the plastic MBUS has more give and resilience properties that make up for the lack of stiffness of an alloy sight. So you can either manage the bend, or be strong enough to prevent the bend. This "test" seems to shows that the MBUS has more resilience than the alloy competition has stiffness. However, you must consider how well this test applies to your application. I have the DD fixed. I like to see a similar test run on fixed rear sights.

That is an unknown. That not being mentioned in the piece leads me to assume that it was not experienced or at the least observed.
I could be wrong though.

While I do have a set of the Magpul's and they have worked well for what I have wanted them for, IE something to run under my ACOG in case it goes down, I don't know if you can honestly say it is better or more durable then the others, or even that the others aren't as durable. A drop test is a drop test, and while it can prove a point I think looking at impacts from other angles would really have been more realistic, from the side, while in the closed position, even strapping the rifle in a press with an anvil drop of varying weights I think would be a better test and grant more insight then a single drop for three different sights.
On a different note, is it just me or did the Diamond back and Troy sights apertures appear to project above the top of the protective ears of the sight more so then the Magpul's? Hence my thought of impacts from different angles then straight up and down.
Just to share some experience with the Matech BUIS, I had one on my M4 when i was in Iraq and was not all too fond of it. It had a tendency to keep popping up after it had seen a little use. Eventually the post on it broke off after about 6 months and i just replaced it with a KAC one that i had sent from home. There was a collection of broken ones that grew as the deployment went on sitting in the arms room. Many soldiers in my platoon would take them off entirely.... not a big sample size but just my exp.
