G+ is, I feel, a more mature group. Or depends on which communities you join and what you're into. I get most of my tech news there as well as tech in education, which is something I'm interested in
I guess it does depend. I found it to be a lot of trolls.
I find the communities and people I circle do make good posts. If I am dissatisfied with certain people or communities, I uncircle them and leave the communities. There are often multiple communities for any given topic. Over time, I find my experience improves as I refind my circles and communities.
