PTFE For Fuel Line - Conductive vs Non-conductive

For those of you who use PTFE hose for fuel line, which type did you go with, conductive or non-conductive? Where did you purchase your hose and hose ends? And how happy are you with them.

I thought all PTFE hose was created equal and just came across an article about the potential dangers of non-conductive hose. Is that a thing, or just a scare tactic?
