Used it first time for mastering last night, the song had some issue's that needed narrow q fixing and naturally equality isn't designed for such usage.
But using it for cut's and shelf's was a joy. I was specially impressed by the shelf's as seem's one can design very detailed curves fast and easy. Same thing goes for the cut's as they can be very gentle when needed. I hope next mix won't need lots of fixing so I can focus better the possibility's equality provides and maybe share 1-2 presets for the community
I prefer span as analyzer though equalitys analyzer helped me notice 1-2 times I needed a correction with multiband comp. rather than eq. More features can be added for it but not a priority.
