Roa75, in a rapid blow out situation MHO is that neither type of tire is better than the other. If a tire blows at speed, just pray for the best. Tubeless are obviously easier to do a temporary repair on in a roadside situation to get you to your destination or back home. There are varying opinions out there on continuing to run on a plugged or patched MC tire. For me, it's different than a car tire running with plugs. On a scooter, you rely on balance to keep you upright and true and you have both a lot less touching the road at speed as well as only one other tire to basically maintain control with if one of them blows/fails at speed. In a cage, you'll have more tires to maintain control of the vehicle with and a larger wheelbase to balance with and recover from a blowout. If the patch/repair on a MC tire fails while riding, you're back in the same situation again with a blowout and hoping for the best.
I've been lucky thus far and not had to deal with a blowout at speed, hope I never have to deal with it either. If I ever puncture a tire on a scooter, it'll be temporarily repaired to get me home and replaced with new rubber every time.
