Have a CG in both my RPA Quad and RPA Quadlite. Both are awesome, fully adjustable and have a true two stage feel. RPA Quadlite uses a CG 2 stage Remington 700 pattern trigger via an adapter hanger so it would be the same as what you are considering.
Peter at Hirsch is great to deal with too.
Never had a Huber so I can't comment. I have Jewels also in both single stage and 2 stage. I don't think they make the 2 stage anymore but it didn't have the feel I was expecting. Its now adjusted back to single stage function only.The Jewels are IMHO precision made excellent triggers, especially in the single stage versions. I have heard people saying that they don't take well to debris and rough field use, all my guns are recreational range guns (see how I avoid admitting to owning safe queens!) so I've never had problems with any triggers malfunctioning ( Except for having a bullet stick in the throat of my RPA and dumping out a case full of N140 when I opened the bolt!)
