Sorry after reading that out loud, that did sound like I was straight up insulting everything other than an RDA. I just meant for my needs, and believe me the novelty 3d rda can't even come close to a kayfun's flavor or warmth, it's a pretty airy vape by that standard. I own and use the squape, Ithaka, and especially the prometheus quite a bit. I'll definitely admit that all three beat the flavor of the 3d hands down, (the Ithaka (albeit lacking in vapor) isn't even in the same universe considering flavor, I've actually had to dilute juices because they were too strong

) but I'm ashamedly a "cloud chaser", I don't feel like it can be my perfect vape without a really good amount of dense vapor. That being said the Squape (after I opened her up to 7/64th" airflow) and the prometheus give pretty much the same amount of vapor if you build it right.
~Out of all the popular RBA's I've tried (lol only 4; kayfun, squape, prometheus and the GG Ithaka), the prometheus gives an AMAZING amount of vapor. It's probably due to the 2 1/8th" airholes, the massive chamber, and the fact that it will feed while your vaping. With a good sub-ohm build it'll seriously gives off MORE vapor than most of my RDA's, while still giving you full bodied flavor and the cooler vape that I like. The thing is built like a kiln, with a tank of juice below it. (Although the wicking didn't keep up with my vaping at first, I drilled the actual wick-holes to 7/64th's to beef up the wicking speed, and it became a completely new animal. Previously I had to hold it upside down for 30 seconds before I could chain vape again (probably because of my thick VG juice), now it has alot of cotton (sometimes mesh) to wick up through with less resistance, and the only time I need to tip is when it gets below half, and if I tip it falls through so easy it's like dripping with a juice bottle attached to the chamber. Easily the best experience I've ever had with an RBA, the squape is great because it will wick fast enough, and not flood every now and then, like my russian 91, it's also got better flavor but really lacks in vapor amount compared to the prometheus or a dripper. The Ithaka is the only "true" RBA I've had to date though, it 100% works the way it's supposed to without any real tampering from me. Although it doesn't produces gobs and gobs of vapor, I couldn't care less just because of the ease of use, and flavor quality. It's the only RBA I've just stuck in my built coils, put the wicks in their slots, and she was ready to go all-day with no flooding, dry hits (probably because it has a juice flow adjuster), leaking, or any wicking problem whatsoever. It's beautifully manufactured, gives a do-able amount of flavorful vapor, and is %100 ready for a long road trip.
~I don't know why I like big vapor so much, it's an expensive (juice-wise) curse, but it's the most satisfying feeling to me to take a 1 second pull, and blow out a dense cloud that can fill a car's trunk. It's the only way for me to get a really smooth hit, and still have that slight nicotine effect. For me the key to my happiness is *more, *lower nicotine e-liquid when it comes down to it. The buzz feels more consistent, stronger yet not a kick to the head like when I vape a device that produces less vapor with higher nicotine content to make up for less delivery vapor. (I only vape 6mg in RDA's/squape/prometheus, and 12mg in everything else, I'm not a nic. fiend or anything

.)
Whoa typed alot more than I meant lol, again sorry to make it sound like "the 3D dripper is 5x better than everything you like" pretty much, those are just for my personal all-around preferences. RBA's/Genni's/Carto's definitely smoke drippers in many ways, especially in ease of use and the flavor category, much less being safer too.
Besides what I should've said anyway (since I pre-ordered one a month ago, and actually received it today!) is that the
Tatroe T1 is a pretty perfect solution for someone who wants the best of both worlds. I've been vaping on mine all day and have nearly emptied the pretty massive
3.7ml pyrex tank above the RDA compartment, first time I've ever done dripping while driving

. It's not 100% self-automated as you actually have to turn the cap yourself to put in however many drops you want, but still a hell of alot more convenient than carrying around a juice bottle, opening it and dripping while your busy. You simply twist the pressure sealed cap to the left until you see a bubble (one drop) come out of the RDA compartment, and then twist back to the right to push that one drop in, easy peasy, and you can still get the great vapor quality of a dripper if that's your thing.
It's the first RDTA (dripping tank atty), and I had to jump on it even though it was a little pricey at $120, but well worth it for the best of both worlds in my opinion. There's no sharing of the negative aspects of both, rather the only con I can come up with is literally only the fact that the big air shaft going from the RDA to the drip tip does condense e-liquid (doesn't steal any vapor though! It vapes as good as even my best RDA's) and that condensed liquid will sometimes leak out if you take off the "cap/tank" off of the deck to look at your coils or whatever. So I just set it down on something absorbent when the cap is off. But it's literally an excellent identical vape from an RDA, with the convenience of a cartomizer/RBA.
