I personally don't have either of those brands, but the pancake holster I carry my SIG P229 in is excellent.
It's a G&G with no thumb strap or active retention, but when it's in - it's in. I like it because it holds its shape pretty well after presentation too - which makes reholstering much easier/smoother.
However, for the money, my Crossbreed's SnapSlide pulls my GSR just as close for concealability, and for a custom made holster costs LESS than the G&G pancake I use for my P229. Something to think about.
