It really depends on your budget mate.
Yes, creamy flavors taste better in certain tanks/atomizer/RTA.
However, for a beginner, I'd suggest going with something simple with a mouth-to-lung (MTL) tank to mimic the tight draw and a 6mg+ juice depending on how heavy a smoker you are/were.
If you don't want to recoil yourself, go with the Aspire Nautilus 2.
If you are serious about stopping analogs, then learn to build your own coils. YouTube is a good source.
The mod only delivers power to your tank. There are the more affordable China mods that do okay like the Pico, and then there is the mid to high range DNA chip devices that does temperature control* (TC) incredibly well, and there is the Ferrari/Lambo class mods Dicodes.
*You can use nickel, titanium and stainless steel (SS) in TC mode. Typically people use SS coils.
TC, explained basically essentially sets a ceiling on how high the coils are able to heat up. In turn avoiding dry hits and some people say a smoother hit.
I used to vape with my ipv 3 li last year, but i cant feel the hit.. so i went back to cigarette. Now i really want to quit it lol
