Welcome, trust me POTV is so helpful, wish i was on here 2 yrs ago when i initially tried to vape.
As others have said it does depend on many factors, mouth to lung, direct to lung, how many u smoke per day, how long u have been smoking, once you decide on the vaping hardware then comes the liquids! I can really help you with that as have tried loads, as everyone else has lol, that's the best part!
Pop to a good vape shop, check out u tube videos, wish i had tried a pod system initially, they are very much like that tight pull u get from a cig. Good luck, use the forum threads to gain info, also use the search function to find related threads. And just ask
Hope my little bit of advice helps, I'm still a noobie myself !
