I’ve tried a few different types of the mesh and I couldn’t notice any difference. I usually go for SS with any coil/mesh just because I have the option to use them in both wattage and TC. I like mesh better than standard coils for the fast ramp up and surface area provide better flavor IMHO but I’ve never noticed any difference in metals used, they all taste the same to me. One caveat, I’ve never tried titanium so can speak to that but the others all taste the same to me.i am biased against Ka1, idk why, guess i read something. but i will get some of the rolls and try em out.
honestly, idk that i could tell the difference between any of them.
