Limited experiences with nozzles and wear

IAfter ~~have printed~~printing hundreds of Kgkilograms of filament through several printers and consequently ~~destroyed~~destroying dozens on nozzles along the ~~way.~~way; I have probably learned nothing, but let's take a look anyway!

Cheap brass nozzles from Aliexpress, Ebay, Amazon, etc.

These can be found in a 10 pack for around $20 USD
- At least 5 are completely usable out of the box
- Usually a couple more can be made functional with some cleanup and deburring
- Never had a complete batch that were all usable out of the box
For this price, it is an OK choice for those willing to tinker and replace nozzles more often
- Had more than one break out the nozzle tip after some long PLA prints
Occasionally seen warping or crumbling after torching out a clog

E3D brass v.6 nozzles

These seem reasonably priced to me at around $5 USD
When I want a brass nozzle for highest quality, this one has great tolerances and longevity (for brass)
Tolerates being torched out after a clog now and then without issues

E3D Hardened Steel and Nozzle X v.6 nozzles

These are quite affordable for Wear Resistant nozzles at around $20 to $30 USD
Raise print temperature (5-10 C) to accommodate it's low thermal conductivity compared to brass
Wear resistant nozzles are REQUIRED to print abrasive materials such as composites (Carbon/Glass Fiber, Glow-In-The-Dark, Sparkles, Wood, Stone, etc.)

Everything else I haven't tried yet

Any opinions I have on other nozzles must be purely based upon the evil marketing strategies of 3D printer nozzle manufacturers

I see low thermal conductivity as the primary failing of my current wear resistant nozzles but unfortunately for me, what I have doesn't have any issues I haven't been able to overcome so I can't justify the eye watering price tag
- Makers of the DiamondBack nozzle claim it has a thermal conductivity comparable to brass
