There's no one best box mod. It depends on your needs and vaping style. If you're going to use commercial coils and vape under 20 watts, I believe that the MVP 20 is your mod. It's simple, solid, dependable and well built and thought out.
If you want to sub-ohm, you'll need a mod that supports sub-ohm coils.
If you are interested in Evolv's new temperature limiting technology and are willing to wind your own nickel coils, I believe Vapor Shark rDNA 40 is a nice choice.
