Former auto user here, I've gone back and forth, but I'm on a manual kick right now. Been vaping for over a year now, and the further in my rear view mirror analogs are, the less I seem to care about simulating the analog experience. Manuals are...
*more reliable for drip-refills
*I tend to take fewer hits (can't be a bad thing, right?)
*my cartos don't look all nasty and chewed up because I don't have the darn thing held in my teeth all the time =)
