I've seen it discussed inside other threads, but I want to see what the consensus is now that the Xi5 has been on the market for a bit. I need more repairs for my current MK w/ Ipilot. It seems like MG may have the advantage on Spot Lock, but what about the other features. I will tell you that MK's runtime on a battery was the main selling point to me before. Anyone that has owned both units, please speak up.
