MCB/RCCB/RCBO: Nano vs CHiNT vs Schneider

I'm struggling with the decision here. The local installer recommended Nano because "It's cheap, works and everybody uses it", while any professional says "cheap crap" use Schneider or ABB only.

I have a fairly good understanding about electrics (and economics) myself, and would go for Schneider, but I'm consulting a friend here with his hotel resort under construction. People say a resort already cost so much money, why cheap out on electrics - while that argument doesn't work in real world. There is no infinite money glitch as we all know 😉

Some stuff is simply overpriced, while CHiNT caught my focus. It's about 1.5 - 2 times the price of Nano, but exists since 1982 and I see it used a lot in commercial large scale solar installations. It's widely used in different countries like Australia, New Zeeland, South Africa, while Nano is solely a thai brand. Chint even won a lawsuit 20 years ago against Schneider for Schneider supposedly infringing their patent.

Found few comments in reddit that CHiNT is "cheap crap" too but no explanation why. Another dude state he's using it for installations in South Africa for over 10 years, and never had issues, and that in this country they are the same price as schneider and abb.
