I have both, and a Bellus. I think the MT has the best airflow and flavor, plus you can fit bigger coils than the Bellus. The Bellus is great, airflow is significantly less than the MT. Flavor is still great. It looks the best of the three in my opinion. The aromamizer was the first I bought of the 3, it has great airflow, but not as much flavor as the Bellus or MT. All 3 are excellent tanks. Seriously, they are all great, but I think I'd recommend the MT first. Bellus and aroma are equal. I haven't tried a crius, but I want to. I haven't had leaking with any, but I got some flooding when refilling on the Bellus and MT until I got the hang of wicking them. If you get the MT I highly recommend a fused Clapton build, it's the best. Can't fit that in the Bellus. 2.5 mm Id. It's unreal!
