You can use mechs for your casual vape. They're durable, no electronics to worry about, and look awesome. But with how cheap a lot of regulated mods are now, I personally no longer see the point in investing in a mech when a comparably priced APV could match, or even surpass the mech's performance. With mechs, you experience voltage drop over time and don't have any power adjustability unless you ran an I-Kick regulator or something.
But this is actually the major reason to use a Kick -- to prevent the voltage drop as the battery declines. If you're looking for something that can easily be adjusted "on the fly," then yeah, a regulated electronic mod is a much better choice; the Kick is adjustable, but you have to open the battery tube and adjust it with a tiny screwdriver, not at all convenient -- so you set the Kick to a level that you generally like, and leave it there, and your vape never declines as the battery discharges. It also functions as a rudimentary fuse -- if the battery went haywire, likely it would blow the Kick which would break the circuit, and give you a reasonable chance to get it out of your hand before it does anything worse.
The Smoktech Kick only goes to 12w, which is more than enough for me, but some might find that too limiting; I believe the eVolve Kick v2 goes to 15w, which gives it much the same power as one of the standard vv/vw devices -- Zmax, Vamo, etc. You don't have to be a sub-ohm vaper to appreciate the good looks and simplicity of a mech, and these non-radical vapers are really who the Kicks are made for -- no, you don't get that huge blast of power with a fresh battery that makes sub-ohm vaping possible, but you also don't have to deal with a continuously-declining vape -- it stays the same until it's time to switch out the battery and recharge.
