For the ball vape, my vote goes to the Phase3 ZXL.
All zirconia build (head an bowl) so the taste is the best it can be imo. Zirconia is more chemically inert than glass or titanium so all you’ll be tasting is your weed. I have a ZX myself.
The rest of my setup is pretty pedestrian. I have a basic PID and I use the SAML FC-Mod for dry cooling which is great but inexpensive if you’re looking for the best. Good luck.
