I am pretty much the opposite. I started with boge cartos and tanks, than I bought some t3's viva novas and a pro tank to try something different. I ended up returning the pro tank. I found when you get a good boge carto thats working right, the flavor and vapor was a lot better than the pro tank. It was more robust with more flavor for me. The t3's and bottom coils to me seem very airy and the vapor is muted and more whispy. So far I like carto tanks better than anything I tried. It just has the right amount of flavor hit and smoothness. I even bought an IGO L and messing with that and i find the hits too harsh and burny. I guess its a to each his own
