I put these on as a replacement for Gatorskins. I bought a 25 for the front and a 28 for the rear (lower pressure, more cushioning, etc.). They seem to roll pretty well and I've had no flats and minimal wear over a few hundred miles. I run them on Velocity A23 rims. The front tire, a nominal 25, measures at 28mm with about 90 psi. However, the rear, a nominal 28, measures at 29 at 90 psi. I'm not sure why the 25 runs at almost the same width on the same rim as the 28. So, if you're thinking of buying some as they close out this model, you might want to take that into consideration.
I put a set of these on before taking on a personal 1,000 miles in one month challenge, last year. They have survived completely unscathed and worked well in the wet, rainy Portland winter. I have previously used Schwalbe Marathons and they are comparable, except for lacking a reflective stripe on the sidewall. Currently our roads and bike lanes are lousy with broken glass. I'm not foolhardy, I don't deliberately ride over that stuff, but I haven't had a single flat in approximately 3,000 miles of commuting and recreational rides. I keep looking at lighter, more expensive tires, but why mess with something that's already working great?
I first bought the Marathon Pus tires (700 x 28) for wet weather and my training bike. I live in New York City and these tires provide me with an enormous amount of trust and confidence against pot holes, steel construction plates, and battered roads. I routinely ride 50 miles or more on all kinds of terrain and surfaces (mostly asphalt and concrete and occasional gravel) and have never had a flat. I bought the same exact tires for my niece. Recently I bought at set of 700x 25 Marathon Plus tires for my custome built $XXXX road bike. These tires have good tread and having more rolling resistance and weight then the Continental Grand Prix (700 x 23) tires that I have rode for more than ten years. You would not want to race on these tires, but they are ideal for dependable safe long rides, and club rides too.
I rode these tires up Mt. Tam on fire roads 3 times in last month and no issues. 2X Eldridge and 1X Railroad Grade and they performed very well despite being taken over rocky terrain that they were not designed for. Zero punctures or cuts and other than a little scuffing they are doing fine. They held better than I expected on loose rocky terrain with minimal slippage. Swapping on some CX tires and will keep these for pavement.
