Concealed with the SME. Or JMC. Or my Sparks EX-RSO at 3:00. There's no way to tell.
In summary, the SME created a more pronounced but rounder bulge with more tuck. The JMC, which does not have the extra tuck feature, conceals just as well; it's a total wash between the two. The shorts in this photo have a bad loop for AIWB, forcing the gun more to the centerline than I think the JMC wants to be; the SME seems to want to be at the centerline, and I think I remember John saying it was supposed to be.
Either conceals adequately but frankly I find I can hide a gun just as well with more comfort in the EX-RSO, and the EX goes with my normal concealment method of a sport coat. I continue to experiment with AIWB (with manual safety guns) but am not an aggressive adopter.
