From what I've heard the titanium or steel or ruby whatever hardened nozzles are better if using really abrasive material like glow in the dark or CF filled or other particle filled filaments (wood etc.). So if looking to mess with more than everyday petg or pla without additives then maybe worth it to save hassle of extra nozzle swaps and having to go through pain of finding out the nozzle has worn through too much and is causing issues.
