Geek Vape Zeus X RTA. (No leaks but no compromise on flavor or vapor).

QP Designs Fatality M25 RTA. (Juiceflow there works).

Geek Vape Creed RTA. (Impossible to choose between best bottom only DL airflow RTA Aqua Master RTA or best side only DL airflow RTA Bellus V2) So would probably go with the best of both worlds and take the Creed RTA.
