I think we will have to choose the lesser of two evils here. Either we get more detail, but we get more ringing and enhanced aliasing. Or we go for a smoother look, but loose detail.
Personally, I would still go with SR7, just because the de-grained look of MagicUp looks waxy and unnatural to me. The clarity of the picture is amazing, and it still benefits being released, as everyone has different tastes and preferences.
You both have done incredible work nevertheless!
