Anything road slick will have good ride quality if you run it squishy.

If you want supple and quick, you'll need to not have all that much flat protection. About the only very supple 26ers I'm aware of are Compass tires; they're reasonably resilient just because they come in wide sizes which can happily be used at low pressure, but there's zero actual flat protection built in.

Paselas are probably still one of the better middle grounds. Schwalbe's Kojak 26x2 might also be appropriate.
