I think it is good to have this discussion on uberSurface related products solely and those are the products that are primarily used in conjunction with DAZ Studio, as the base shaders come along with it.
That was always a problem of pwSurface2 - while it is an excellent shader by itself, it never was part of the DAZ Studio base and due to that never got used as much as the uber-related products. uberSurface2 has also the ‘problem’ of a reduced market share (as it has to be bought) and due to that less information being around (and presets). The tricky part with uberSurface2 is primarily that said shader reacts very differently compared to the original uberSurface, but the transfer preset does a decent job for that.
In the end, the generic uberSurface is actually quite good already and I think community wise it’d be best to focus on that. I agree with you there.
