^ I record live music events. I have zero need for timecode. I think that is probably true for most taperssection members. Balanced outputs aren't really useful for me either. The MixPre-6 has a much better user interface, XLR line inputs, and better metering. It is also considerably smaller (80.85 vs. 42.51 cu in) and lighter (1030 vs. 564 g), which is an important factor for my use. Additionally, I like knowing that I have Sound Devices' customer service behind me; that is worth a bit of extra cash, in my opinion.
Like I said, "Different strokes and all. Each has advantages and disadvantages compared to the other." If you don't need timecode, the superior interface alone might be enough to tip the balance...
