The Maxx has internal logging, so you dont need an external device. The EMU does if you add the EDL-1 unit. However, once you start adding all the external modules, the cost advantage really starts to go away.
I think it really depends on wire-in vs plug-in. If you are doing plug-in, then you are kind of using a bit of blunt tool (batch injection, limited sensor inputs and data collection) so it kind of makes CAN logging a bit silly. If you are going wire-in, and dedicating all that time and effort to replacing everything and going full sequential, monitoring pressures and temperatures at every point, then its silly not to collect and analyze that data.
Regarding the LSU sensors, almost everyone I have talked to says there is not much of a difference from a usage standpoint (when looking at the standard sensors), but the older 4.2 may be a bit more robust a sensor from a lifecycle standpoint. The 4.9 is not leaps and bounds a better sensor or anything. It is more important that the sensor is implemented properly in the hardware than which it uses. The EMU does not use the Bosch driver IC inside the Black, it instead uses a proprietary discrete input (unlike their Lambda-to-CAN module which is considerably more expensive as it adheres to Bosch design). In any case, I would take any ECU with internal WBO2 controller over an external CAN any day, as all the latency, coms problems... etc are avoided.
