No joking: this

High ranking players all support the SuPen, for which the official PaD stylus is based off of.

I've owned about 4-5 styli. Rubber styli can ruin your screen (as it did to my Nexus 5) after long periods of play. The official PaD (and I suspect the SuPen as well) stylus is the best out of all the stylus I bought.
