Been through the first wing maybe only a dozen times since November so my experience is limited.
GF is still as packed as ever it was. I used to really like GF some years ago when I'm sure it wasn't as busy as now, pre and post covid. The seating should be better laid out, lots of wasted space still.
I would definitely recommend the b gates lounge vs a packed GF lounge, as The_Banking_Scot above says.
The CCR does appear to be quieter now, than it was pre covid. I was a touch concerned with the addition of all GGL it would make the place busy.
To me the best thing about the CCR is that it's quiet and peaceful. And of course the employees there.
So I'm pleased to see the balance in reduction of F seats and the addition of all GGL has in no way impacted the CCR's charm.
