I use:

Schwalbe Marathons on my touring bike: enough good has been said about these and I have experienced one flat over I don't knowhow many kilometers and it took a huge chunk of glass to cause what was a small puncture and a slow leak.

Schwalbe Silento II on my commuter: These are new to me... they roll out and ride very well at 65 psi and as they are a trekking tyre have a low side lug for non paved roads. Mine are 1.75 rear and 1.50 front and the handling on wet and dry roads has been stellar and they are about as quiet a tyre I have ever run. I give them a big plus in the ride department.

Schwalbe Hurricanes: 26 by 2.0 semi slick with more aggressive side lugs for more off road adventures but a very fast rolling road tyre at 75 psi and have never flatted in over more than 10,000 km and they still look nearly as good as new.

Have tried the Kenda Kwest but after running Schwalbes for so many years and miles these feel like I am riding in mud.

I have some Specialized Fatboys which are pure slicks that I need to test... friends have used them and tell me that few tyres roll as fast and they are high psi 26 inch slicks.
