well in all fairness your smds are more like jumbo COBs ;)

the disadvantage of SMDs are the obvious labor involved in assembling a bunch of discrete diodes. you solved that with an affordable assembly

both are really really efficient when driven at insanely low currents, and i think your boards prob win on heat dissipation alone on the low low side
