I hate and love both.
Squadrons can be levelled outside of dungeons, do more than just dungeons, are comstumizable, and the few dungeons they do well (the not too mechanics-heavy ones are really nice with them.
Trusts are great the first run through, but levelling them is a horrible nightmare and I'm honestly giving up on that, at least for now. And they're not customizable at all. They don't make you facepalm as much as squadrons, but they also do stupid things cause AI.
And yeah, I think the most important thing of both is not so much the skipped queue and pug, but the ability to be able to practice your skills in comfort and learn your class well, as well as learning the dungeon mechanics perfectly, both things that don't happen as much in a PUG.
I'd honestly want a mix of the two.
