i think the holes on the smok's are too small, although i've not had a problem with my juices, because i don't tend to use heavy vg juice. however, i think i like the boge cartos better for some reason. the quality issue has been addressed, and the ones that were "bad" are pretty much long gone. i punch my own for the most part, but i do love those nice sized drilled style holes you get with some boges from a few vendors. the flange on the end of the smok cartos is pretty darn cool, but since i've been using cartomaters and higher quality tanks, i haven't had any issues with tanks slipping. i have and use both, but for the most part, i lean towards the boges
...and of course, Ikenvape cartos are also in a class of their own... when you can get 'em.
