I've been using 316l SS coils on Taifun GT clones for 2 years. It doesn't give a warmer vape. On the contrary, it's a soft but full vapor. As it has less resistance, you can use a thinner wire and it heats up fast, but mild.
I like the way it enhances the soft vape of the taifuns for some juices.
I haven't tried it yet on a TC mod (my only tc mod being the istick, I suppose it wouldn't work on TC mode unless I twist it with some pure nickel... ?)
I also like its softness (not as soft as ni200, but much more than same gauge kanthal). I find it easy to coil, though it also means it can break more easily than kanthal when you overtighten the screws.
