The G930's are a gaming headset, and they are actually good for a number of reasons, but they also have a number of drawbacks.
I'd default to the G930's. They lasted me about 2 years before they started to die on me and they have programmable buttons to activate push to talk voice chat while you walk around the house which is something almost no one else offers. They are also incredibly comfortable. I got Astro A50's and there are a few annoying buzzing sounds that like to come out of the right ear when the mic picks up any sound. I don't recall the G930 having any issue like that.
Do be aware, though, that the G930 has some disconnect issues. It'll randomly disconnect and reconnect as it gets older. Some have a huge issue with it and some don't have any issue at all with it. It just depends on which one you happen to get.
