For 22mm atties:
1) Revolt from Canada(people are really sleeping by not getting this thing, easy to build and a reduced chamber puts out really nice flavor, but mostly the build quality/materials/finish make it my number one. From grub screws that doesn't back out with rounded bottoms so your thinner wires don't get clipped to PEEK everywhere even a top cap all PEEK option that can really protect from insanely hot builds, to lead free/oxygen free copper center post with available stainless steel included, this is my number one without a doubt. A very classy and tradition design atty with massive attention to detail for those with an eye to spot it.)
2) Origen V3 from Hungary (insane build quality and vertical coils make this a must own piece especially for collectors that want to experience a genisis style RDA. You can use any wicking material even mesh and still come out on top. The airflow cators to people who like a more restrictive flow especially when building single coils. Either a 1.2mm hole and really nice airflow for those who build duals allowing 1.2 all the way up to 2.5 duals meaning 5mm. And finally the heat fins make this thing look so clean and sophisticated at the same time. With a bottom feeding option for squonkersso you can have a ton of juice without needing to constantly re drip, this thing is solid! My number 2 just because building on it isn't as easy as the classic tri post design.)
3) Velocity from USA (unique deck with a massive well granting a lot of space for variable coil builds and massive juice well for stuffing all the wick you need, this thing is a exotic builders must have, and a simple builders must have. Airflow control that is really innovative and highly tailored, it can accommodate all sorts of settings. Having no posts to get in the way of the airflow allows side airflow to be free to do what it needs to without vapor shooting up against any posts. Quality is too notch and the only con I have is the comp cap is a Delrin screw on that might wear away as time goes on, but being thick threads this might not really be a concern. A bottom feeding pun is coming soon so squonkers galore. That's my number 3 tied with number 4 really.)
4) Viking V2 from USA (Amazing quality as well like the others with 2 airflow tubes that shoot air under the 2 or 1 coil you may build. Lots of room and choice when it comes to building. But what really does it for me is the look and good juice capacity and the insane flavor from bottom directly to the top airflow, the flavor is just top notch. It reminds me of the Kennedy RDA with just a little better aesthetics. It's my number 4 because it's nearly impossible to get when it sells out, shame it's not more popular, this is a flavor a RDA with massive potential for a ton of clouds when built right.)
5) Geyser from the Philipenes (I had to include a cloud chaser in this mix since I gravitate toward many flavor atomisers. This is an atty I haven't seen copied by others too much. It's a quad coil based even though you can do one or two coils. What I like about it is the drip tip it comes with, stock that produces amazing flavor since the airflow comes from the bottom, but since you have quads it also makes a lot of clouds. The second optional cap is the competition cap that adds air from the sides for those who really want to push a lot of heat and air around. Very small atty for what it is. It also makes dripping so easy since it has a pyramid like Teflon pieces in the middle that distributes drips of juice to the four sides of the wick and coils, so you never need to remove the top cap. The only downside of this thing aside from brass deck, is the juice capacity is very small (no well, the cotton holds the juice for a few drops for a few massive hits, and when going to competitions, you really don't need anymore if your looking to win, which you will if you push the limit with your build on this thing.)
