My $ 0.02, in order recommended above. I don't squonk or use rda's so no comment on those.
1. Dvarw- very nice vape, but odd engineering on the 2 PC chimney, with a removable cap that sometimes sticks in the top, sometimes on the lower portion of the chimney. I really do like the vape on this one, but all the parts remind me of a Kayfun. Also reminiscent of a Kayfun in that the wick has to be near perfect over the holes in the lower sleeve. For me, it has a great vape, but doesn't offer anything over a doggy. But it's a good tank, compact, nice looking - it was just a step backward, design wise, from the doggy, in my opinion.
2. Kayfun Prime- I love Kayfun (especially KM3), and was very disappointed in this one. Very well designed, except that the vape quality was more "diluted" and not as condensed as the KM3 that preceded it. Never could get a decent throat hit out of it. I wanted to love it, but gave up after many tries at every conceivable build, and gave it away.
3. Doggystyle - sets the standard. Started with the SXK, and it couldn't be more flawless. Easy to build, no jfc to worry about, very few parts, delivers a consistently great vape, with my requisite TH. Never a leak, never a gurgle, never a dry hit, never an issue ever. Tried the SJMY version, and found it has everything above, but greater airflow without sacrificing density or throat hit. It became my favorite. Used doggies for almost a year, and really thought nothing could improve on it.
4. Berserker. Tried it, but didn't own it. Very tight draw, pretty good. Way too many leaking, gurgling issues seen on this forum for me to consider buying. Many say top fill causes real issues, and resort to using bottom fill, or a multi-step fill process. And I liked the vape on doggy better.
5. Siren- again, tried but didn't own. Pretty good, but not better than doggy, and had enough reported issues that prevented me from buying. And I didn't like the vape better than doggy or I'd have bought it.
6. True MTL - recently won it from Heavens Gifts, and didn't think much of it, until I tried it. It is seriously the best vape I've ever had. Better than the Doggy. Similar size, but lower capacity. But it does have top flow, an upgrade over the doggy's bottom fill. Even though it doggy's bottom fill never bothered me, I really do like the easy top flow of the True - and it lets you fill to total capacity easily. I always vaped the doggy completely open, but many didn't like the airflow ring on it. Doggy doesn't have a stop, and really is hard to dial it down if you like tighter af. The True is really easy to do, has stops, and multiple af options. And closing it down to almost nothing really works, without making it vape like it doesn't want to do that. And it's tight - if you close it, there's no air escaping thru there. It leaked on my first try, but I found I just didn't tighten enough, since the doggy doesn't require that, and it was what I was used to. Since then, no issues. Just rebuilt easily (super easy build with wire trapping, which the doggy doesn't have), and haven't had any other issues - no seepage, no gurgling, dry hits, nothing to criticize at all. Dry as a bone underneath. Like the doggy, but unlike Berserker and others, there's no juice control to worry about. I have no desire to deal with that after Kayfuns. Couldn't count the times I'd singe a wick after refilling, and forgetting to re-open it. Or get gurgling if I forgot to close it when filling. If a tank wicks right, there's no need for jfc. And I vape all vg. I'm loving this tank, and have found a replacement/upgrade over the doggy. It isn't expensive at all, so anyone that MTL's should really give this one a try. Standard is 2ml, but comes with a bubble tank to take it to 3ml. I build it 28g SS, 2mm ID, 7 wraps, 0.58ohm (same as I do doggy), and it's fantastic. My beloved doggies just haven't been getting much use since I got it. I haven't tried any of the prebuilt coils that come with it. Aesthetics - who cares, it's compact, solid and vapes great.
7. EXpromizer V3fire - never heard of it.
