Everything's a compromise, and I pick which compromise I want based on how I'm using my gun. My class/SHTF AR SBR has an adjustable BCG with an A5H2 buffer; my competition rifle has an adjustable GB with an A5H0 buffer. The competition rifle is a bit picky about what it eats, but that SBR is reliable under all circumstances I've ever tried it in. OTOH, that competition rifle doesn't move under recoil, so I think I can live with that.
I will look into the Seekins and Noveske blocks for future uppers.
