I concur! I've got a buddy who got me into
vaping, and to return the favor, I got him into sub-ohming some months later. The STM was his first foray into wrapping <1 coils, after I had great success with the Subtank Plus.
We got another friend of ours a set up, the Mini with the Cool Fire IV. It's probably the closest thing to idiot proof we could have done.
What I love about the Mini (as well as my Subtank Plus), you can use the RBA section, or the replacement coils if you don't feel comfortable with building your own. Or, you know, if you're feeling terribly lazy, as I often am lol.
At any rate, buy the Subtank Mini. You will not be disappointed.
