Does the filament path of ruby nozzles degrade + is DUROZZLE any good? (infosec.pub)

I'm thinkin about getting one of those ruby nozzles for my printers to basically be able to print anything without ever having to worry about a degrading nozzle. I've seen quite a few videos about it, but I still don't know two things:

Given the surrounding material is brass and only the tip being out of ruby, doesn't the filament path where the molten filament gets pushed through still wear out over time (heavily so with CF or GF filament)?

And also

How good are the cheaper ones, specifically the "DUROZZLE" one (since that's the one I could find that's 0.6mm and cheap)?

Ruby nozzles are alright. I ran them for several years on my printer. But they can break if you aren't careful. I broke mine well cleaning a clog by accidentally applying pressure sideways with my cleaning tool. Broke a chip off the tip.

I ran lots of carbon fiber, iron and steel hybrids, and glass fiber through my nozzle without any noticeable wear.

I ran the expensive Olsen Ruby, not sure how Durozzle compares.
