Mydnight, here is my experience of Xiping and Gande Ti Kuan Yin
difference.
Xiping Ti Kuan Yin: The soup is more heavy than the gande, which is the
very important characteristics of traditional ti kuan yin. The smel is
also very traditional for us to taste. The soup color is heavier than
Gande Ti Kuan Yin, which means "Kou Gan" and "hui Gan" is better.

Gande Ti Kuan Yin: The smell is much strong than Xiping Ti Kuan Yin,
the leaf is more green(is very fresh), beautiful than some green tea I
think.Below is the tea leaf brewing I took with Gande Ti Kuan Yin.

I will show you more picture for the difference.

For me it is still very difficult to tell the difference for the two
kinds of teas, the best way to know it is to try the two teas.
