Just settled this argument personally myself, and I went with the G3 two main reasons A. sound quality the G3 just sounds better all round, good because I mostly work on films that can be reshot if something goes wrong with the transmission but the quality can't be changed. B. spares, repairs and durability if I need a Cos-11 with G3 wiring it wont be that hard to find, but with the sony wiring it could be a nightmare or the other way round renting a G3 is painless and I can keep using my accessoires. From other people I have heard the battery pack of the Sony is less durable and could break, Pink Noise Systems who sold it to me said they have only ever had like 20 out of 4000 of the G3s they sold come back and only ever for minor reasons like sticky buttons or bent ariels. The question is do you really need the benefits of a true diversity system.
