Just been doing some reading on the 6L80E and it still seems a little to unknown.
Lack of aftermarket TCM, the need to active torque management of the engine, all sounds like a ballache for now benefit?

The 6L's TCM is programmable, just more complex. And as it's built into the trans, it is essentially free. Find a good tuner or lower your input torque expectations. At 600HP, you utilize an almost stock calibration. Torque management is awesome, just sophisticated. The 4L based 6X, as it is a step-gear design, is an absolute no-brainer from an install standpoint.
You asked about shift speed, rally style performance, parasitic loss and DCT style functionality. To that end, the 6L has the performance benefit, by far. Except for the tunnel mod and 800HP cal, the process has become surprisingly straightforward. I personally am a little shocked at how many people are going 6L.
