You're simply hypersensitive to ceramic my dude, no need to overthink it. There's a lot of people on this board sensitive to all sorts of different things in vapor. If your sensitivity is ceramic, that alright, it's not for you, but you've said what you needed to say on that matter, lets stay chill before the mods get here and have to start playing clean up.
Everything you say about this Peak has been said by others about other ceramic atomizers. You're really not alone, but realize only a minority will be as sensitive to ceramic as you. For others, it's metal, or silicone, or wood, or all sorts of other things in the vapor path. Lets be respectful of each others sensitivities and recognize that we all are a little different here.
For me, temperature controlled draws off my Divine Tribe V3 ceramic donut are still probably the best tasting dabs I've EVER had, and I have a SiC Halo, e-nail powered HE Gavel, etc. Taste is subjective - it's normal to have different opinions on what tastes better.
