The Omni and any TI version is best, as it allows for the best airflow. But, the M is a damn nice vape too and for the price can't be beat. Id recommend getting both, but the all TI version is best in class. It is a very different beast than the SV3 but i personally use the VC much more often. The VC is faster to use, and has a very unique vapor profile that utilizes convection, conduction, and radiant heat. It is obviously a great portable, but can hold it's own at home. It doesn't take up much space. It is amazing how cool the vapor is considering the short vapor path. I love the SV3 but the vapor comes in very hot if you don't use it with a water tool. @Gray Area the Lotus is a great vape too but is pure convection and thus not ideal for hard hash and concentrates IMO. I have found vapes that use both conduction and convection are superior for all hard concentrates.
