Both will work pretty much the same but with different issues.
JOHN DEERE SERVICE ADVISOR PORT SOFTWARE
I switched places channel 1 with channel 2 (see the pic) with my Chinese version and now it works fine, probably it was possible to do it adjusting the software settings as mentioned above, but i tried a lot, and nothing helped.

If you are prepared for this here is what you have to do: Connection establishment is taking a long long time and you never see the ECU. Every time you establish the connection u have to remove the usb plug and plug it again for the readings to appear. Programming controllers is easy, but diagnostics is a bit annoying. From my experience only the older machines have it and still can be programmed most of the time. Lots of machines don’t even have a 3rd Powetrain channel. I reprogrammed all the controllers on 6690 premium except two, but found a way around it opening the pld file with pldeditor and changing Powertrain channel to Vehicle (channel 1). The 3rd one is Powertrain and it is used very seldom. The thing is that Nexiq has only 2 channels while EDL has 3. I spent a month doing research on this and i managed my Chinese Nexiq to work 90%.
JOHN DEERE SERVICE ADVISOR PORT INSTALL
Install windows 7 and then can put my image. My suggestion, buy used Lenovo T400 or T500. The image will not work on xp, but SA works fine. And every time i change my laptop, i just restore it. If you have a Lenovo Thinkpad laptop, the easiest way is to restore the main partition from the image of my computers’ c: drive. It is possible to install John Deere Service Advisor on your laptop, though the installation is really complicated. Topic 1: John deere SA possible with Nexiq usb link?

FYI, John Deere Service Advisor 90% works with Nexiq China clone.
