How long would you say this coating lasts? I suppose that the brand would also play a difference. Which is best?
I've heard that some don't last long at all, even less than anti glare coating.

The thermal or UV cured as long as the lenses. The dye vat applied, until the lenses are cleaned.
No eyeglass lenses — not even glass lenses — are scratch-proof. However, lenses that are treated front and back with a clear, scratch-resistant coating have a much harder surface that is more resistant to scratching, whether from dropping your glasses on the floor or occasionally cleaning them with a paper towel.
