You know most diesel engines in semi tractors mount their ECM directly to the block, right?

No I didn't know that, did you know that a ton of flour would make a big f#ckin cake? 
Seriously I haven't worked on any tractors new enough to have an ECM. I do know they mount some of the newer vehicle ECMs in the engine compartment, but I also know the amount of harsh testing they put underhood electronics through with pressure and cycle testing and hot and/cold fluid dunking cycles etc to simulate all sorts of scenarios, in addition to vibration isolation mounts, multiple chemical testing, etc since I used to work for a supplier of automotive sensors for GM and Chrysler.
I also find your comment kind of funny. I guess because they put it on the block in slow moving diesel tractors means on top the intake in a high speed gas automotive application must be the perfect place to put it. And are they diesel ECMs mounted with rubber mounts and most of them are open engine compartments and have the exhaust on the opposite side? I also usually don't see carbs mounted with isolation mounts and I am sure diesels produce many high frequency vibrations and a lot of high pressure water spay from all the high speed evasive maneuvers tractors are capable of.
Now, in your defense, MSD has probably done their homework and sealed it up and potted it and it will be a reliable system, great. But that still limits the ECM to only control that particular throttle body and injectors. The FAST system you can tell it to control up to 8 injectors (in the intake or two TBs) and tell it how big the injectors are since you can use whichever injectors suit your engine. Will this matter to most people, I don't know, maybe not. Heck, it might not even matter to me because I don't plan to change my intake soon and if I get another EFI system it will be a fully programmable sytem so I can control a boosted application. But to have the capability will surely matter to some people, and if I ever take the EZ-EFI off the truck and put it somewhere else, its nice to have that option.

Semi tractors. Not agricultural equipment. All of those semis running down the interstate. I can see the rest of your points, I just wouldn't be worried about the ECM on the engine.

OK, you got me there, I didn't see the "semi" word (I actually looked back to see if you edited it). I guess your comment isn't so funny now as they have similar conditions to regular vehicles except for the vibration frequency.
I guess in the long run both choices are good to have, because I am sure the atomic will be better for some as the integrated timing will be more important than the higher flow and increased optional capability of the EZ. Its another trade-off.
