Hi Salmo. I don't have that particular model of reel from Redington, but I have the Delta & the Rise reels from them (as well as 3 rods & waders). I like their products; I find them extremely high-quality for their price-point.
My two cents is I don't think you'd be disappointed by them.
I have a Redington reel, I think it is a GD, but mine is black. Works great! baught it 4 years ago now, more then enough strentgh with a 30+lb salmon on her last fall. Never washed it or greased it as always intended to buy a high quality reel. Had baught it as a starter when I got into salmon fishing.... I think I might have to wash and grease her good and keep her for a while. Well worth the money in my opinion.
I have a 6wt and 9wt Redington Rise setup/combo. I've caught a lot of fish on the 9wt and it's a champ. Won't beat it for the price. Can't speak to the GD, but my experience with Redington has be great.
I have a CD reel 9/10 wt with an RS4 rod that I find to be a fine combo. The Redington brand seems to be great, I've never heard a negative comment so far. I'd say the GD would be good also and should be at a bargain price since it's been discontiued.
