With the thermal conductivity of SiC so much higher than sapphire, for what reason do people seem to prefer sapphire?
SiC and Obsidian are best for cloud chasing.
Sapphire is more chemically inert and provides a more nuanced flavor profile (while still providing nice clouds).
I would say from an overall price/durability/efficiency/taste standpoint SiC/Obsidian win as Sapphire is quite a bit more expensive and fragile.
But ... once you get a Sapphire insert I doubt will ever use anything else.
YMMV.
