You can get an entire replacement Crapality hotend kit for $26 if you're in the US. https://www.amazon.com/dp/B09NKWJ35T/ Imo, if its not broke and I don't have a specific need for it I'm not going to do it. The highest quality parts on my machine are my extruder, nozzle and heat-break. The rest of the stuff works well enough, and replacement parts are cheap if I need them. Really its subjective. Creality doesn't make high standard machines but they work for what they are.
