I have lily and the mighty
Lily pros- instant heat, can be used as a one hitter, great for conserving your stash, butane powered, great for replicating the smoking feel, easy to set up, beautiful wood body
Lily cons- the periscope becomes very hot, takes a minute or two to fully put away once done vaping (unless have a way to cool the periscope a bit faster), requires two hands to use, can be harsh on the throat,
Mighty pros- no draw restriction, consistent big clouds, great taste first hit or two, pretty decent battery life (haven't used many battery powered to compare too), reclaim from the cooling unit, fast extraction of goodies, temp control, pretty smooth on the inhale, gets the job done fast, get the brush that I love with it
Cons- having to charge it lol, chance of having issues with unit(broken fins, error 004), non replacable batteries, heat up time (though only like a minute thirty, still not instant like lily), consistant cooking of herb ( kinda puts a rush on vaping, which to me is a plus at times and a minus at others), shut off timer is two minute if cant reset it with your draw(easy to turn back on quickly though), and I cough a lot on the exhale even with the smoothness though pretty sure that's just me
Probably more I can't think of cause can't use either atm, and havent used any of the others so cant put input into them, but hope was able to help you a little bit
