This is really good... quality of outer sole, inner sole, laces and last but not least grip, everything is good...
The one thing, that is best in this is, the power cushion. Because of the extra layer of cushion at the heel, it give extra comfort even when you are lunging and your ankle has to take all the load and because of that extra cushion, load does not carry up to your leg, thigh... which is a problem in other shoes, irrespective it is any other Yonex shoes or may Adidas or Asics.
