    It’s difficult to see exactly since the reference board image is quite blurry, but they seem to have the same components. Apart from the fact that the Shenzhen one has what appear to be gain switches which is useful if you don’t have an Arduino and it also has a heatsink which may or may not be helpful since it’s designed to be run without one.

    So I’d say, whichever is cheapest depending on your region. One thing for sure though, the reference board is designed by the chipmakers so they should know what they are doing with the layout more so than Shenzhen, but that I do not know for sure. Maybe the layout differences only affect the size, but there is a possibility of slight detriment to audio quality, but I doubt it would make any noticeable difference either way.
