Well first has come in, it is a single 21700 Dovpo Evolv DNA 75. Enjoying it with an old rda (dead rabbit), but it is heating up the battery a bit (it is warm in my hand). I have a Lost Vape Grus 100w that has not come in so far - it is not a DNA, but seems to have replaced the Mirage (that I had wanted, but did not get before it was discontinued).
The Pod Mod is a Smok RPM 2
https://www.elementvape.com/smok-rpm-2. Got one to give to my brother in law and one to play with myself. Added a high ohm coil to the basket to play with salt nic, as the low ohm ones will probably be way to much for me for that that. My stepson is using an RPM Pro 80 right now, and his girlfriend is using the older RMP 40. the 40 is much smaller, and the RPM 2 (which is also 80 watts iirc) is somewhat in between. The Pro 80 just seems to much of a compromise for me - as I have great mods already and only wanted something smaller and better to introduce my brother in law to (I don't think he wants to deal with the size of a mod or the complexity of anything rebuild-able.
That said, my wife has a Nord 2 I think - but it is not getting used much. It would probably have been a better starter for my brother in law, but I did not add one to the cart. I was going to try to get him to use my wife's first. As he is coming from cigarettes, the MTL of the Nord would probably be a better fit, oh well - I don't do much MTL...

For what it's worth, I have a Centaurus (DNA 250) It replaced my Paranormal (that died), and an Aegis Legend also sitting within reach and in my current rotation. That are toped with mesh RTA's (a Profile Unity and a Zeus). A Kennedy is also sitting somewhere close - but I stole the battery out of it to play with the Evolv.
Yes, this is not unlike black rifle disease.

Ok defining terms...
Original vape systems were not high tech. You controlled wattage by changing the resistance of the systems heating coil (and understanding a bit about ohms law, the resistance of wire, etc...). They consisted of an atomizer and a mod (these simple mods are called mech mods now). The most simple atomizer was a coil of wire filled with a wick - which you dripped (D) a few drops of juice on. Since this was prehistoric, you tended to rebuild things yourself (often making your own wicks and your own coils) This idea is now called rebuildibles (R). So a Rebuildable Drip Atomizer is an RDA. Now I don't know the complete evolution from then on, but eventually a lot of things changed. Tanks (T) were often added to the atomizer so you did not have to drip (now we have a RTA). At some point mods also became smart - they had circuitry to protect them from draining the battery too far and to allow the user to control the current without needing to use ohms law and changing coils. Some also use temp control, allow the wattage to changed during the puff, etc. Some got pretty smart. DNA is generally considered one of the best circuitry.
Going back in time a little, the only source of nicotine was freebase nic that the cigarette company had been using for decades to increase the nic level of cigarettes. It had a limitation. It had a hard throat hit - nobody could enjoy anything strong than 12mg. Then the parent company of Juul figured out salt based nic. It had much less throat hit - people could tolerate up to 50mg. This allowed smaller lower power devices to give a decent puff. Juul made a system that had a self contained, disposable cartridge (pod), so the user did not have to worry about coils or wicks, or power levels.
Simplicity was contagious, plus the vape companies realized there was a lot more profit to be made by selling pre made wick/coil systems rather than letting people rebuild their own - so most atomizers started using systems that had more expensive, but simpler premade wick/coil systems. Meanwhile, competitors also understood there was a niche for small refillable devices, so refillable pod systems were born.
So Now we will get to the Nord (about 2 years ago I think). It is a pod system, but with a replaceable wick/coil. They incorporated some of the advances in the circuitry so you could set wattage, likewise you could use different premade wick/coils inside it's pod. This is the begging of the blending of pod and mod systems (there are other brands, I have no clue what came first) - but it was still a fairly small salt nic based system. Then they created a stronger unit, then a stronger one... Eventaully you got the RPM's - Real Pod Mod (they wanted to advertise it was a hybrid system). By the time the RPM 2 was out, it had enough power to use freebase nic. It is no longer tiny, but still smaller than almost any mod - plus using the pods and premade coil/wick systems it is fairly braindead to use.
Now mod system users will probably say the RPM is a dead end. Real mods are better, plus allow the user to use any common size (510) atomizer. There are unlimited options, especially when you go to the rebuildables. That said, pods are a LOT cheaper than atomizers, and pop in coils are super easy to change out. I think they have a place in the world. The only issue is that they tend to have a lot more open airflow and tend to be more orriented to freebase nic - but it is my limited understanding that they can still use the old Nord coils (designed for salts), and a piece of cellophane tape can cut back the airflow to at least get the draw closer to a mouth to lung (harder pull) rather than a direct lung (open pull - usually used with mods). Oh, and they hold more than 2x the juice as a Nord pod.
I am sorry if this is rambling and any of it is not 100% correct. But it should give you enough information to research it yourself. While not universal - the crux is pod devices are cheep and easy to use, and are more a nic delivery system than a cloud making machine (it is what gave vaping a bad name - kids trying to secretly vape in school). Mod based systems can have more flavor, big clouds, and still give whatever level of nic you want. Pod Mods are a transition device - simple and easy to use, but depending on their coils can theoretically use either juice. (well so can a mod's atomizer, but nobody does that really - as mods are much larger than pod devices).
Oh and one last thing. I ordered this stuff online with black Friday pricing. Lets just say the 2 RPM's and the Grus were about the same prices as 1 RPM 2 bough locally (abet I did not need to buy any batteries, atomizer, or charger for the Grus. I bled a little on the Evolv DNA, somewhat more on the Centaurus. Meanwhile, the Aegis Zeus is really a remarkable mod at a rather affordable online price (just a little more than the Grus) - but you still need to add the battery, atomizer, charger, well the pod mod is a lot cheaper point of entry into something that is almost a mod.
