i have the CTAC and love it
it stays put very well (dont need to constantly adjust it and realign it while you are wearing it)
it is comfortable enough to wear all day and then some (ive had mine on my side for almost 48 straight hours with no discomfort)
i like that it is tuckable (sometimes you simply have to tuck the shirt)
its very thin and holds the gun close, so it doesnt print much and doesnt bulge out one side of your waist band like some other holsters ive tried do (hard to conceal when you have what looks like an 8lb tumor on your hip)
it draws very fast
it holds its shape so reholstering is as easy and smooth as drawing (no fussing around and forcing needed, simple one handed use)
its flexible where it needs to be so it forms well to pretty much anybody
