I was checking those out, and for the money I think id go for the Pico at that point. I believe the atty deck is shorter since its below the battery end line, plus you can use the arcticfox firmware which is awesome on my eVic Basic.
I use a smaller diameter tank for the SBody, as the edges of the mod are curved and 22mm tanks overhang a bit (due to the curve), but as a light-weight, low-wattage, small carry DNA it's perfect. Only does nickel TC though.
The Pico is my favorite form factor (I have 9 of them!

) that fits 22mm tanks perfectly (some 23mm will fit though). Handles TCR, Ni, Ti, & SS TC, so more versatile. I haven't delved too deeply into the AF software myself. Tried it once and found it difficult to change settings on the mod without changing things within the PC software. Maybe I was missing something in the menus/button clicks. I went back to Eleaf software until I learn more.
