Hi and welcome! The beginning of the journey can be quite confusing. I actually didn't pick my first hardware set up, our 20 year old daughter brought home two Smok Stick V8 kits with the Big Baby beast and asked us to just try it.
I smoked 2 PAD for 23 years. In two weeks I was done with the cigarette for good. The Big baby V8 kit from Smok that you mentioned is amazing. I did upgrade to another mod, the Tesla 120 w with temp control but I really need only use it occasionally and use the stick all day everyday. But I really like tube mods, so I'm getting my first mech next week. But that requires some studying on ohms law and battery safety is huge.
I guess what I am saying is, the Smok Stick is excellent. The Big baby hits hard and with the right juice I'm am sure it could really get you in the road to quitting and it's also a piece of kit that more than likely you will continue to use even when you upgrade.
Good luck and please let us know how it works out for you.
Oh, and a huge thing for me was I NEEDED a liquid that tasted like tobacco and I still do. When I first quit using the Big Baby with it being sub ohm I was using 12mg within 2 weeks, 9 and then quickly to 6. I'm at 6mg now and very happy. And I still only Smoke Tobacco NETs and hybrids.
