I have now tried both and I do not agree with Prince's measurements.
The Wilson grip is supposed to be 1.6mm thick and the Prince 1.5mm, but the Prince feels much thicker. Uncut it is shorter than the Wilson and weighs 31g compared to the uncut longer Wilson at 24g.
The Wilson also wraps much better and easier and feels nicer.
My choice is Wilson by a long way.
