Whats better tubeless tires or tubes...im confused or one tire tubeless?

In some ways, tubeless tires are more flat resistant than tires with tubes. They are not prone to pinch flats, and if you run them with the proper sealant, small punctures seal themselves, you only need top up the small amount of air you lose when you get the puncture. Very small punctures may not even be noticed, so little air is lost. If you are still worried, you can carry a tube with you, and if you get a puncture that does not self seal, simply remove the valve, put your tube in, and finish your ride with the tube. With good tires, flats are not a very big problem.
