No doubt you've discovered it'll be hard to find a case that everybody likes equally. I've tried an Apple leather case, an Apple silicone case and a clear tech21 case sold through the Apple store. All had the same issues for me, and that is poor touch sensitivity on the buttons. I went with a no name soft clear case for about 10 dollars. Good grip, easy breezy button feedback but so-so protection on the front around the bezel, and it hasn't yellowed so far.
As an aside I'm pretty sure Apple is rehashing the 6 plus leather cases as compatible with the 6S plus, but in my opinion they don't fit the same.
