I have no experience with the others, but I just finished a hot 2.7 build with the Electromotive XDI 2.
Twin plug, cams, carbs, I called Richard and asked if he had a program that would get me off the ground running. He asked for a few parameters and emailed me a personal bin file, for my engine. He said it would get me 90+ percent where I would want to be.

The wiring was straight forward and I followed the instructions to the T. Uploaded my bin file, removed the fuses while I cranked up oil pressure, then with fuses in and fuel pump on, cranked and she fired right up and purred at idle. Shocked me, it sounds like an injected car.

I need to put some miles on it for a good reference, but it seems like quality equipment, and Richard Clewett support has been great. The software is very user friendly, but I think they would have files for almost anything you would want to build.
