That's basically it in a nutshell. The ceramic heats really slowly and your flavor is cooking off before the rest is hot enough. The terps that do not boil at those lower temps are oxidizing slowly and will not all taste the same by the time they do boil. A major downside of this is that all of the subsequent hits after your donut has started heating up are going to start to taste shitty rapidly. I loathe the taste of subsequent hits on ceramic oil pens - it tastes like overcooked garbage and I'd rather not finish the bowl! Typically half of the bowl remains at this point too! Think of how much of the main higher boiling actives are being wasted here?
IME Ceramic pens are like quartz nails - waste it to taste it or do high temp awful tasting cloudy rips. Fuck that! My dab rig reclaim is much tastier on a nail than the 3rd hit of the best flower rosin in such a pen (I am not exaggerating)!
I have still not found a pen that I continue to use on an ongoing basis. The all white ceramic style carts do not clean properly IME (white porous ceramic ends up with disgusting baked in residue that is nearly impossible to remove, even with something like the puffco+ that you can qtip). I don't wanna go from perfectly clean rig and nail hits every time (I clean the whole thing every day!) to dirty pen hits because it is too hard to get a pen sufficiently clean (read: LIKE BRAND NEW).
Coil based pens never get clean, the coil wicks up the fucking iso and you have to heat the coil forever to get rid of all the iso. The coils obviously collect gunk which tastes like burned ass too. Pens atm take too long to clean (and rarely clean to the extent I demand) to be suitable for somebody who requires the utmost hygiene in their oil setup like myself.
Don't get me started on these pens not working properly with full melt too. Even the coil-less pens taste like ass.
If you wanna improve flavor, you will have to go to sapphire now. Otherwise, SiC is the best place to be
