I haven't really been too active on Google plus, but recently I found myself really getting in to it again.
Personally I prefer G+
In my opinion:
It is so much cleaner and uncluttered, not to mention way more organized.
It has better sharing options so I don't have to have people see things I don't want them to see. If I only want a few people to see a post, it is really simple to do that.
The chat is better in terms of quality and features (and videochat)
I could keep going, but I think you see my point of why I like it.
My ONLY gripe with it is that I don't think that enough people caught on to it / are using it. I think if more people used it it would be a much more useful site.
Which do you prefer? And why?
