My old nx I had Michelin latitude sports for the summer and Hankook's in the winter and both were great.
On the RX I have the bridgestones and they are super quiet and smooth, almost like air but stopping in wet is not as good as other brands. I put Yoko V906s on in the winter and though they are a bit more softer and not as "air" like to ride on, the grip is very good.
It all depends on what you want. Comfort, lower rolling resistance, better handling in wet or dry, stopping in wet or dry, aquaplaning, fuel efficiency. It is all so subjective.
It also depends on how you drive, what you drive on e,g motorway, A roads, country roads, town driving etc.
