Just a 6-month update on the PBR Deluxe pads on the 300SE.
All is good so far.
I'm still amazed at the minimal amount of dust.
No measurable rotor wear with my micrometer (only 2k miles).
They do require maybe 5-10% more pedal effort when stone cold.
When warmed up, they feel perfectly normal.
No issues in the rain, perfectly normal.
Tried an engine-off stop with no vacuum boost - much harder pedal and couldn't lock them up, but about what I have experienced in other cars. (never tried this with OEM pads).

The rears have the Pagid, and are still squealing and dusting; can't wait to get the PBR on them also.

Oh, one last selling point for me: I discovered my Corvette has PBR brakes as OEM.
