...If you are only riding road, stay away from tubeless all together...
Maybe you had some bad luck or poor sealant or tires combination.
I ride tubeless tires on my road bike for about 3-4 years now.
This year so far without a flat for ~8,400km.
With Orange sealant, the regular one. And GP5000 tires.
Tubeless rims have a special bead profile that retains better the tire on it.
And in the center has a deeper groove for an easier mount.
