I believe the T-Servs are heavier duty, I've put mine through some crazy hard riding (ie gravel centuries) and never had an issue. My Paselas will never see anything but typical road conditions, since I won't take that bike on any crazy rides.
I use T-servs on my commuter bikes (26 x1.75) and regularly roll over broken glass, although not by choice. After two years, no flats to speak of. I think they are great tires.
