Here's my insight into Buzzy, for whatever it's worth:
My first submission to them was a very light, very adventure-oriented urban fantasy story, which they bought.
My second submission to them was a sequel to the above-mentioned story, with the same main character, which (I think) is better than the first story. I got a form rejection for that one.
A few weeks afterward, I got to meet the two owners/editors of Buzzy Magazine in person at a local convention. They were a pleasure to talk to, and they mentioned that they brought on an editor who, in their words "is much tougher than we are."
So the stories you're seeing being published now were originally accepted by Joy and June, who are no longer directly involved in the selection process. I *think* the new editor is Laura Ann Gilman, but I've never interacted with her directly or know her preferences. The one R I got from her was signed Buzzy Staff.
One final data point: My third and current submission is a humor fantasy story (think Robert Aspin) and it's at 33 days, so it may have at least survived the first round of consideration (as they sent out dozens of Rs today) so I hope that the estimation about them enjoying light fluffy stories is a good one because there aren't as many great markets for those, and I love writing/reading them personally.
