I use an x nozzle. As far as I understand the zodiac and X are similar materials and likely close in workmanship. I would be curious if you try both if you see a difference. Personally I suspect they are very close.
My x is as well. I have not noticed filament sticking to it however, The apeture seems perfect still, and no extra stringing! It has paid for itself in the speed I normally replace brass ones.
Just broke off today my 0.4tungsten as last night it came loose a little bit mid print after a swaped it (my bad for not tightening good), just tryied to tight it up a little more to keep printing and planning on taking apart today to inspect … Broke up when trying to take it off, I must of thightned it too good last night!
Still have my old nozzle X, might give a try to a Zodiac in few month
