I have always preferred 18350 mods because of the size. Battery life and power isn't as good as an 18650, but it's just so much more pocketable IMO, and I like the look of smaller mods as well. Though with a dripper, I'm starting to think a 18500 would be more practical.
What would you say is the size you use the most throughout the day on average?
