No, for
dual 18650 battery regulated mod at 40-70 watts, stick with the Sony/Murata VTC6 or Samsung 30Q, and, if you are concerned about causing extra wear and tear on the batteries each time when you vape on your dual 18650 battery regulated mod at 70 watts, especially if the batteries tend to get fairly warm due to how you vape, either you should try to avoid letting them get warm (i.e., wait longer between puffs to give the batteries enough time to cool back down again some, as they age faster than normal, or what's considered to be normal, if you regularly let them get warmer than 45 degrees Celsius, or 113 degrees Fahrenheit) or you should consider getting the Molicel P26A. That's just because the Molicel P26A heats up significantly slower in comparison, if you vape at 70 watts on a dual 18650 battery regulated mod.
In addition to this, the fact that the Molicel P26A has a lower capacity rating of only 2600mAh (compared to 3000mAh for the Sony/Murata VTC6 or Samsung 30Q) is rendered completely moot somewhere not very far above the 70 watts mark on a dual 18650 battery regulated mod. That's because, at such a higher wattage level, as you go further up in wattage the Molicel P26A wastes so much less energy in comparison, it actually even makes up for that, when it comes to how long it takes before you need to put the batteries back on the charger.
Whereas, if you vape at only 40 watts on a dual 18650 battery regulated mod, then the Sony/Murata VTC6 or Samsung 30Q will heat up so slowly that accelerated aging of the batteries will be a nonissue, when compared to the time it takes before you need to put the batteries back on the charger.
Should you need/want more vaping time still, going for a dual 21700 battery regulated mod will be your best bet. I own an Odin DNA 250C mod, and, I never vape on it because I only use it to dry fire some of my beefiest super low ohm complex coil builds that I occasionally like to experiment with, but it's a really nice mod that should easily get you through the day vaping at 70 watts if using it with a pair of Molicel P42A batteries. In addition, the Molicel P42A heats up even slower than the Molicel P26A does, so it should be able to last for several many years if you don't set the charging rate on your battery charger too high and you also take good care of the batteries.
Finally, I don't know what it is you don't like about RDAs. RDAs with decent handbuilt coils in them are quite literally the only reason why I stopped smoking burning tobacco cigarettes. With an RDA, it's easy to vape the cotton wicks almost dry (but not completely dry) so it never leaks. Also, there's no glass that can break, and, the best RDAs can produce so much better flavor compared to any tank with drop in coils, the difference really is like night and day. Where I live, a good pair of handbuilt 28/36 Ni80 alien coils retails for only 15 Euros right now, albeit I can build them myself with my cordless drill and my swivel tool. When handled correctly, these coils last multiple times longer than any drop in coil.
Granted, there is a bit of a learning curve as for how to mount them in an RDA, how to position them, how to dry fire them, how to wick it up, and how to clean them each time when you rewick. But you don't need to be a rocket scientist to get there. When I picked up vaping in January 2017, I didn't know anything about how to properly use an RDA. There's only one "secret": don't hesitate to ask people for help whenever you need help, but always beware of those who aren't very knowledgeable about the stuff that they try to teach on others, thinking they are smart or possibly faking it. (I could be wrong, but... I suspect that one of the main reasons why you had to spend $1,000 and kept pitfalling was because you fell victim to the classical-old phenomenon known as "internet trolling" on several many occasions that could have been avoided specifically by asking for better/real advice a little bit sooner TBH.)
