Why are Hager RCBO's so popular? (domestic)

Serious question, but why are people happy to spend so much more on Hager breakers?

They're around $10 more with tails which to me seems a lot if you're fitting off a new installation ~twice a week

I've always been a fan of Hager products, they look great and the quality has always been great but if its going to save me $100 on a board I find it hard to justify.

Generally I stick with Voltex or clipsal resiMax but I feel like I am missing something as I see them so often.
