I would say it is preferred, based mostly on taste or flavor. Dry sift generally has better terpene profile. Better smell/taste. Easier to "sprinkle" on your bud. Some people complain about effecient ways of smoking bubble. Most dispensaries prefer pressed, and many patients are unsure of how to smoke the pressed hash. That what I have found anyway.
I would say bubble has the ability to be high potency, due to less "filler" or plant material. Matt posted results of 51% THC IIRC. I do not think dry sift could get that high, but I could be wrong. I think there is also much more to it, then a simple THC level, so maybe the terpenes in the dry sift make up for it? Not sure.
Some people like making dry sift, then taking those buds and using them for edibles after getting the kif. Dry sift wont get all the resin, so you have some left to work with.
As a casual run, I'd say dry sift is more convenient. If you have a tumbler, throw it it, tumble for a short while, collect. Bubble has a couple extra steps due to water. Still super easy and chill.
Maybe get the tumbler this time around. Later on, grab a couple bubblebags. Then you can go back and forth depending on your stash, and preference. Just a thought.
