I had a Sidearmor for my Glock 29, I sold it last month. It was a good holster, well made and comfortable. I wanted to try out a Comp-tac, so I sold the Sidearmor and got the Comp-tac Gurkha. I have only gotten to play with it a bit as it is a Christmas gift. I put it on and had a few practice draws. My initial reaction is it is more stable than the Sidearmor, and seems to be as comfortable, will know more once I actually wear it for an extended period of time.
I also purchased a Comp-tac CTAC that I sent payment for today.
As for cant angle, I prefer 15-20 degrees. The Gurkha is 15, the CTAC is adjustable from 0-25 and the sidearmors can be had in various cants.
The CTAC may be a good option, that way you can play with the cant angles.
I would say either sidearmor or Comp-tac would be a winning choice. Both CT and SA make quality Kydex.
