Which is better Hansgrohe vs grohe shower fixtures?

The brief history seems to be like this:

Hans Grohe founded the company. Later the son sold the brand to an American corporation and set up his own company again. This time round he cannot use hansgrohe, so he used the brand grohe instead. As for which is better, I have not had the chance to compare them.

But based on first touch alone, Grohe taps are somewhat smoother when turning them on/off compared to hansgrohe, but the price is very much different!

Hansgrohe is the original company created by Hans Grohe. His son created Grohe and made Hansgrohe specialise in showers and Grohe in mixers (or faucets). Then Klaus Grohe, current CEO of Hans Grohe took control of the company and Grohe got sold (and has been sold numerous times). Hansgrohe is still owned by the Grohe family, but Klau's side! The showers and taps by Hansgrohe are the best, no question.
