My touring bike has Schwalbe Marathon (not Plus) tires. One flat in over 5000 miles. I don't think the extra weight & expense of the plus version is worthwhile.

My single-speed, that I commute on often has the Pasela Tourguard tires. No flats yet, but only a couple of hundred miles so far. Before that, it had the plain Paselas, and I had several flats in about 800 miles.

I've had a number of Continental tires, and was never satisfied with them.
