I only carry the G26 AIWB unless I'm at the range qualifying with the sheriff's office...so I can't provide any good info other than people seem to love Tony's IWB #3, I believe.
The "George" is one of Tony's AIWB holsters. It's a little slimmer in profile, (less waistline bulge), in comparison with the AIWB model. I have one in G19 size that works great for the 26.
Otherwise, I primarily carry AIWB with one of my two DSG Orions in G17 size, regardless of which Glock I carry.
