Sorry, but tubeless shines in road applications. Well, unless you like actually enjoy fixing flats when you could be riding. I haven’t had a flat cost me as much as one second in well over 10,000 miles of riding. Judging by the sealant boogers on both my front and back tires, I would have fixed dozens of flats with tubes tires. I don’t even carry a spare tube, plugs or even a pump any more.

If the OP only gets a flat once every three years or so, yeah tubeless probably isn’t a big deal. But for those of us who ride in areas where they get lots of punctures, tubeless is great.

Effectiveness at dealing with larger punctures also depends on using good sealant. As another poster mentioned, Stan’s hasn’t worked so great for me. Orange seal has worked perfectly.
