I have at least 8000 miles on various Continental GP 5000 tubless tires (both TL and S TR) in sizes 25mm- 32mm, every ride starts in the city, and have yet to have a puncture that didn't seal up on it's own. I frequently encounter broken glass/grit and other urban nastiness on my rides and with tubes I'd get flats every few months. Now I never get flats.
I wouldn't buy the TL version anymore because they're extremely difficult to mount. The S TR solves that problem. I'm sure other tires would be fine too, but I see no reason to buy something that is specifically "puncture resistant" for a tubeless setup.
YMMV
