Sure it's like trying to decide between a sedan a van and a truck while also considering every make of those vehicles all at once.
Personally my plan was to get a iBTanked tank, a small mix of Cartos pre punched preferably of the Bogue brand, a vision ViVi Nova, and a AGA RBA. From my own research people like the Bogue cartos well, ibtanked came highly recommended, and the vision vivis are supposed to be a good brand of clearos. And really the AGA is just affordable to see how I can handle the RBA.
There's too much variety in the vape hobby for me to feel like I know what would work for me by reading alone. So I opted to try one well liked type of each option.
