Well the mod matters too. I mean, I've been surprised at the way different atomizers perform or not just by switching mods.
Ultimately, your best and smoothest vape (IMHO) is going to be a DNA mod, by a wide margin.
Which one you decide is best for you, and whether the price tag is worth it, only you can decide.
I will say, mod makers I like who do a decent job of delivering consistent, smooth power include: Teslacigs, Eleaf (to an extent) Innoken, and the Ages Legend, just kind of Generally.
But you aren't going to beat a DNA mod for a smooth, consistent vape whether you are using TC or not.
Good luck deciding.
