I'd say that fragility is about on par between BPPC and CSPPC cards, however CSPPC is a better card simply because it offers:
SCSI-3, 64-bit memory access, and 604e cpu.
vs the BPPC which offers:
Fast SCSI-2, 32-bit memory access, and 603e cpu.
A big plus for A1200 nowadays is that if the motherboard breaks, a replacement is easier to get than A3000/A4000 motherboards.
