You really don't know much about debanding with gradfun3, Mister Hatt, do you? Trust me, adjusting gradfun3's parameters is useful, especially if you aren't going the 16bit route. Before adding grain, it's better to make the gradients smoother, and adjusting the parameters will change what is recognized as banding and how it will get fixed, and results can vary wildly. Grain is good and all, but it can't quite fix banding on its own, at most it hides it partially, and even then you'd have to overdo it to have it actually have an effect, so it really is no solution on its own.
