I've got the Logitech g933s in the UK and the corsair Void Wireless in Sweden, both are decent, although you can hear the Audio quality difference between the two. Not enough to bother you, but it is noticeable.
That being said I personally prefer the mic of the voids, but I use a Røde NT-USB with the 933s. The Void does a much better job of cutting out the ambient sounds where the Logitech doesn't appear to do much towards that.
The logitechs are a fair bit heavier than the corsair, although the logitechs feel a lot more sturdy than the corsairs.
The wireless range seems to be better on the logitechs, although it's difficult to gauge in two different places with different objects around. That being said both have no difficulty transmitting from rooms adjacent to the pc.
Depending on how you like things the 933 offers a lot more flexibility, you can have up to 3 simultaneous inputs. (I have only ever used two) to have for example; games on the pc and Spotify on your phone, or gaming on pc and TS on your laptop or gaming on your console and Skype on your pc. I tend to use it for gaming while talking to the missus on FaceTime which works very well. Mixing can be done via the Logitech app on the pc.
