well, I didn't find any more attys to add to the list after finalizing the search by going through all of Fasttech's "atomizers".
I think fasttech is just screwed up or something:
If I just type in "RTA" on the main page, it says there's 499 results, 394 of them in the category "Atomizers", 76 in "misc accessories", the other ~25 in random categories like "drip tips", "coil heads" etc.
So ok I go to the Atomizer category to look though them all, apparently there's many more which aren't listed though. The 499 items make up 8 pages I looked through them all and didn't see most of the ones I already listed but they are listed on Fasttech. And if I search those items separately, they show up in the Atomizer category (and also have "RTA" attached to their names). So I dunno what the problem is. If I search "Zeus rta", it'll show it in the Atomizer category, but if I go through all 8 pages of the 395 atomizers, the Zeus isn't there.
But, I don't think there's even anything I missed worth while for me or those looking for 24-25mm ish RTA that are mostly stout and not too tall, and that accommodate big coils like fused claptons.
As mentioned, I basically voided out all attys with small wire holes meant mostly for single strand wire because I use fused claptons, but can still use thin single strand wire in a large velocity deck or similar).

Wait, so you made a "list of what I think are the most worthwhile current RTAs in 24-25mm or similar range" for others to use, but you haven't tried any of them and are asking for advice on which one(s) to buy? ... lol
So are you still searching for an RTA(s)? I know of two that I didn't see on your list of the most worthwhile current RTAs that I think you might enjoy more than the ones you listed (judging by your posts).
The OBS Nano Engine (not the standard or the mini). Top airflow directed from the side, 5ml+ capacity, and is 25mm.
The Wake RTA is also a good option for you since it's a rebuildable tank that can also use pre-made coil heads, but it is bottom airflow. (I'd personally go with the Nano).
I didn't use any of those tanks listed other than the TFV8 and Gemini, but I watched a lot of reviews which were mostly all positives, and saw the star ratings and don't think I listed any POS or defective tanks.
YES! the OBS Engine (nano and standard) are great tanks, thanks for pointing out that I missed that. I might actually get one of those too.
The reason it's not on the list is because it ended up in my "sub ohm tank" folder simply as "OBS Engine", and I didn't yet search about sub ohm tanks which use premade coils to have figure out that there are RTA-only Engines.
It ended up categorized as a sub tank because I must have done a google image search for simply OBS Engine (first thing I did was look at pictures) and saw the premade coil next to it along with the other RBA pictures and probably figured it was a RBA that can also use Premade coils (like TFV8s), but there's about 4 different Engine tanks.
Or I saw the premade coils when "OBS Engine" is searched on Fasttech.
There are probably at least a few others which ended up in my sub ohm folder but might be RTA-only versions because of this same confusion, but I would have listed them with these later.
Besides the TFV8 that I listed as an RTA, any sub ohm tanks which also have an RBA deck I'll list as a sub-ohm tank though.
But thanks for pointing out that the Standard OBS engine (and 25mm nano, and 23mm mini) are RBA-only.
OBS Engine RTA Standard 25mm: dual velocity, 25x54.5 w/ tip confirmed by manufacturer's 'parameters" graphic, 5.3ml, leak proof top air.
OBS Engine Nano RTA 25mm: single, 5.3 ml 25x54.5 w tip confirmed by saw in manual during review most likely means w/ included tip because Standard version was confirmed same size with tip. Leak proof top air. (identical to standard version besides dual vs single coil deck).
OBS Engine Mini RTA 23mm: dual velocity 3.5ml 23X54.5 w/ tip most likely. Leak proof top air. Basically identical to the Standard dual velocity version but is 23mm instead of 25mm hence the 3.5ml vs 5.3ml.
