Has no-one really upgraded their brake pads on their mk6?
I'm sure plenty have mate, but for a wider response on something like brake pad choice and reviews you'll be better off hitting a mk5 forum tbh...
Brakes are the same with the exception of a change to a smaller rear disc and Bosch calipers on the mk6, all pad fitments are the same

Seems people havent got round to modding the mk6 to quite the same extent as the mk5 yet, but I've had In no particular order:
Ferodo DS performance: great upgrade from stock and retain Reg90 approval and therefore road legal, around £110ish
Ferodo DS2500: a step up from DS perf and capable of light track work, a little noisy at times and give off quite a bit of dust, technically not road legal as lacking reg90 approval but a great all rounder, £150ish
Mintex M1144: same compound performance level as DS2500 but without the judder you can get due to pad transfer with the 2500s on track, great for fast road and light track work, again technically not road legal, around £100
HTH
