What glock do i buy?

I want a glock 19 that is optics cut, and the only one i can find is the SRC glock 19 gen 5 MOS. The thing is ive seen people say that src is shit, and to go with VFC. But I cant find any VFC glock 19 gen 5's with an optics cut. They are both elite force, but I dont want to get a gun thats gonna be bad quality.
