Hexane is a pain in the ass to purge off and hazardous why do you use that method?
Well everything has been said...oh well here goes 1 more time. The differences between butane iso co2 etoh and anything I forgot is minimal after the processing you end up with "pure" thc and crap.. The more washes you do the less flavorfull, for example I prefer the qwiso method then winterizing with etoh then doin a super saturated saline/hexane wash to remove the last of impurities.
Really the difference is ease of smoking (butter) and taste.budder unlike amber still has waxes and icky lipids that can make the smoke harsher and congest your lungs...
Just my 2cents
