RDS for Glock RMR vs RMRcc

[4l65e]

I'm trying to decide which optic to have a slide milled for and thought y'all might have some experience, this will be my first handgun optic.

The dot will be going onto a Glock 19, and I'd like to have a lower 1/3 cowitness or maybe even lower 1/4 if possible.
I like that the RMRcc is a touch thinner than the RMR, and there wouldn't be any overhang on the sides of the slide. Just don't know if it's worth giving up the glass size.

Anyone used both?
