Kho Gen Do from Sephora is well know as the best cotton for wicking your coil. The problem is that it is expensive. I set Geisha from Japanese Organic Cotton next to some Kho Gen Do in a different ecig and I did not notice any difference. I used different wattages between 10-100. I used a Galaxy by Surric vapor RBA on a Sigilei on the to review this cotton. It holds up to all wattages. For less than half of its competitor it tastes exactly the same. You can get Geisha Organic Cotton through their FB store here or their web store for slightly more here.
