As far as best TH and vapor in the standard models, people are
always going to disagree. Personally I like 510s for vapor (especially with VG juice!) and KR808s for flavor; I find throat hit depends more on the juice than on the atomizer. Some people like the 901s or 801s better, I just have no experience with them. (You'll hear a lot of 510 proponents like that -- they started with the 510 and stayed there.)
But the general advice for the best TH and best vapor from whatever atomizer you like is to get a
high-voltage mod as your battery power (people generally like 5v or 6v for the "sweet spot"). There are a
lot of quality choices out there for you: Prodigy, Chuck, Silver Bullet, Xhaler, GG, GLV, and others I can't think of right now I'm sure... They all require around a $100 investment or more to begin, and you still have to use a standard atomizer (510, 901, 801, KR808, etc). But if you're looking for the "best throat hit and best vapor" and you don't mind a bigger piece of equipment, the HV mods are the consensus favorites. (As to which one, I'm not even gonna say which I own, for fear of starting a catfight...
