Well, the G930 and G35 are pretty much identical except the former is wireless and the latter wired. I have both G930 and G430 headsets and the G930 definitely has better sound despite having the same 40mm drivers IMO... but it's also more expensive. I've never had any complaints about the mic on either G930 or G430 so no problems there. The G930 automatically mutes the mic when you lift the boom though, and the G430 has a switch on the cable to mute, so the G930/G35 win that one too.
I guess it comes down to price. If you can afford the G930/G35 then don't get the G430. If you need wireless, then get the G930 over the G35.
