VapCap is very cool, but very 'hands on' - lots of technique involved. it also needs a torch (unless you get the induction heater thing), which makes it pretty conspicuous in public. easy to combust, and the tip gets very hot - spacing out can be a problem with this one... people who miss the whole flame ritual (pipes and bongs) like VCs. MFLB is a great device, but also pretty demanding: you have to shake it every hit. this means that each hit tastes a little less good - and to truly finish a load means re-vaping the already-vaped bits along with the not-yet-vaped specks, i.e. not tasty! mighty: easy to use, great flavor, no technique required, no stirring needed. I have all three. I never use the MFLB anymore, only use the VC for hard hash (mighty's one weak spot: it doesn't get hot enough for this, although it's fine with bubble hash). mighty's my go-to.
