I've used both and to be honest find it difficult to chose between them on either performance or construction. The buttons on the G3 can be broken if the pack is in a pocket and the person sits on a hard edge, where the buttons protruding a little take all the weight and do suffer a bit. On the other hand, the scan feature I never find useful. In my experience, all it does is tell you a channel is empty at that moment – so doesn't guarantee it will stay that way! I tend to use the banks, so if I'm only running one of the many I have, I turn it on, on the frequency it was last on – and only change if I hear something with the squelch backed off. The scan I know people love, but for me – pointless. If you ever break anything – Sennheiser bits and pieces are easier to find, here in the UK. Shure's also annoy me with channel display rather than frequency – small point, but looking at a channel number doesn't make checking other people's gear simple.
