Both are quality holsters that will serve you well. You might as well have a Ford vs Chevy debate.
Try them both...see what works for you.
I will ask--in what kind of environment are you going to be using the holster. The reason I ask is--the drop leg holster (as a whole), sucks when you are in a seated position a lot of the time (either in a vehicle or at a desk).
Just my 2 cents...
