I think blowouts are pretty rare nowdays. But on the road a nail in a tubeless is absolutely easier to deal with. I use
Ride-On which is suppose to work much better in tubeless, but you have to pull out whatever caused the flat to really make it work.
I'd still hesitate to ride a repaired tubeless to the end of its useful life where a flat in a tube, a new tube will go you to the end of the tire or the next flat.
