Have both and carry both some. I carry AIWB almost always, and the RAMI does conceal better in this method of carry for me if i am wearing more form fitting clothing. On the rare occurance that I OWB carry it is the P-01. They both shoot excellent, but the P-01 is my preferance for an extended range session. Most of my wardrobe allows me conceal either just fine and I carry my p-07 the most, so I would say P-01 so long as you can conceal it fine.
