I had GRS with Brassard a bit over two years ago - so I've had exactly the same procedure done by the same surgeon, if that helps.

I had no visible scarring outside the vagina (I'm told by a doctor with a speculum that there *was* some scarring inside as well) except for one line up the center of each of the outer labia, about 2" long and maybe a quarter inch wide. By six months the scars had faded to pink, and by now they're basically white and vanish into the skin folds. I'll admit that pubic hair hides the remainder, but even without it the only person likely to notice would be my wife or doctor; someone has to be looking at it from inches away with a good light source and a sharp eye to tell that it's scarring rather than natural variation.
Bear in mind, too, that in order to see the full of your outer labia at all, you'd have to be lying back with your legs spread. While standing or sitting, the entire area that Brassard leaves any scarring at all is entirely invisible and hidden by your thighs even if you're naked.
I did lose a couple of stitches early in the fourchette and that was red and raw for a while, but it didn't scar - once it was fully healed it was normal skin toned.
