I'll confine my comments to the Lavabox DNA200 and not make any comparisons to the others since I am not familiar with them.
While a bit large, it does fit in my stubby, fat fingered, and arthritic hands quite comfortably. All the tanks, including the Kanger Sub fit nicely on it and the all black with the black TFV4 mini looks rather nice (to me anyway). The texture of the changeable grip gives it a secure feel for my sometimes numb hands. I really like the feel and looks of the mod.
As far as battery life, I am in a bit of a different situation then many making it hard to give a lifespan. Then again, that is a big part of why I went with it. Trying to keep this short, I will just say I am retired and spend most of my time at home and usually in front of my computer where it is easy to plug it in and still be able to vape away. And I tend to only use it for the parts of the day when needing power of 80 watts or so. I should probably just use it all day sometime whether at 80 watts or using one of my 30 watt tanks and see what I get out of it. A big plus for me was the availability of replacement batteries, which was a main factor in going with mods using 18650 batteries on my last 3 mods.
I won't get into the operation and functions as I assume all DNA200 mods are fairly similar. I will say that at first having to learn the button sequences to make changes in settings seemed a bit daunting, but my old mind picked it up pretty quickly. And since I am just now getting into temp control, I am not familiar enough to give any advice or suggestions about those features. But I am really looking forward to trying all that out.
Hope you can find some bit of help in all that. And my best suggestion would be, if possible, stop in a vape shop and put your hands on whatever interests you and get some good, free advice. Just because you looked there doesn't mean you have to buy there. But the Lavabox was the first thing I was able to buy at my favorite shop at the same price as online.
