consider the mvp type first, get some experience with it, try out some mechs with friends that have them, base an opinion on them and if you like them, then buy one...
kinda like ... learn to drive a car with an automatic transmission, once you feel good about driving then try out a manual transmission vehicle...![]()
My thoughts run counter to this for the vehicular, if you learn to drive a manual transmission first you can drive anything, any time.
However for vaping, I'd say the obvious go to starting point should be a VV/VW type device for any person who is looking to quit smoking. If you are entering vaping for no particular reason attached to a preexistent addiction then mechanical mods are the more involving choice that a hobbiest might like to start with.
Either choice can be effective, the VV/VW device is simply less reliant on user understanding of electric theory and application than the mechanical device which requires the user to be at the very least familiar with the basic concepts and willing to follow a few reasonable rules for the sake of both safety and vape quality.
