about hardened 3d printer nozzles? Which one should I get

The current setup is original Prusa Mini+ with [an oem replacement for the] default 0.4mm brass nozzle, Bondtech heatbreak and uh Some Kind of Copper Heater Block [I don't know what brand because the website I bought it from during pandemic shortages was awful]

I mainly want to try some metallic filaments and maybe nylon and/or carbon fiber stuff but I'll probably still be mostly printing PETG and PLA... I remember reading that the hardened steel ones are less heat conductive and make it harder to print lower-temperature stuff, is that something I should worry about?

in reply to @masklayer's post:

I've been learning about this, but haven't bought one yet.

the Obsidian (there's an x in there somewhere idk) nozzles claim not to need a temp adjustment, at least for the Nextruder versions.

Tungsten Carbide nozzles have similar thermal properties as brass and are extremely hard. however this can mean they damage the threads in the heatblock when tightening. i think ppl upgrade to a copper heatblock to use TC.

the nozzle X seems to have several downsides and is not preferred.

go for it! at least one brand of TC nozzles has a lifetime warranty because they are indestructable.

Obxidian uses inserts or something to try to have both the hardness and the thermal properties, but TC seems like the real deal.

also I've heard weird things about the ruby. i think its not lined all the way up and the metal part can wear?
