I preferred smoktech carto's over boge and ikenvape before I started using a
tank. With a
tank though I'm leaning more towards boge. The boge's are harder to fill the first time but they don't flood like the smoktech's did in a tank. I'm guessing the denser filling helps keep them from flooding easily. Unfortunately I haven't had a chance to try ikenvape's in a tank as they're always sold out.
