For the chaps using all these cartridges and other weird concentrates, why wouldn't you just use a dry herb vape and use good old bud? Cheaper and you know you actually getting weed and not something else. Also tastes way better, I can't stand the taste of dabs.
I think the difference between carts and dry herb is quite substantial all round - and neither is better than the other, they serve different needs. I for one am thankful that we have the choice nowadays.
Liquids are very convenient for certain activities (movies, and other social events, as mentioned), but the effects are different than vaping or smoking dry herb (which themselves can have a fair amount of difference depending on vaporizer used and temp settings).
Another problem with dry herb (unless you grow and store your own) is quality can vary greatly from one batch to the next (even from the same supplier).
Dry herb, at least the way I vape it, is definitely much more cost effective, but at the same time it's a hassle with prepping and cleaning, etc. While the "ritual" of prepping dry herb cab be fun, it gets old after you've done it a couple of thousand times, at least it has for me.
I grow my own plants, and I also do my own extracts - using alcohol extraction or with my rosin press. I've made juices that were near pure cannabis (not quite as pure as HV carts, but close enough), and others diluted with PG/VG, sometimes with added flavouring (like a normal vape juice) which you can vape next to anyone and they will have no idea that you're vaping cannabis - these diluted juices are also quite mild and nice for micro-dosing all day long.
To me it comes down to situation. When I'm home I tend to favour dry herb in my PAX. When I'm out and about I tend to lean more towards the liquids.
I think if the extraction was easier, or the retail cost a bit lower, I'd use a lot more carts/liquids, purely because of the convenience factor (I'm lazy that way).
For me, one of the most limiting factors of the liquids is the relatively small selection of strains - I'm very particular about the strains I use, and most of our suppliers don't have my favourites (Green Crack, Northern Lights, Strawberry Cough)...so I end up having to grow them myself and make liquids, which is quite tedious, so I end up just vaping the flower.
