Haltech is proven whereas AEM is a newcomer.
The AEM offers faster performance, plug and play with the wiring harness, onboard dataloging (ie without a laptop), integration of several systems into one CPU wich is more reliable, etc.... The downside is BOTH systems require you run a seperate boost controller and the fuel maps on the AEM aren't as mature (ie pick you map based on the mods you have).
Haltech is definitly proven, there are fuel maps & extensions to work with a 3rd set of injectors, 3 rotors, etc.. You can pretty much get 95% efficiency by download a fuel map based on your mods. (ie little tuning).
Haltech requires you to run a second wiring harness or splice into your OEM harness. Most people agree you'd want to do some of this with the AEM even though it's PNP. Basically you'd want upgraded/more efficient sensors to work with both systems (O2, air/fuel, etc..).
The Haltech requires 3 or 4 boxes to do it right if I remember correctly.
Anyway that's what my R&Ds turned up. I'll probably go with the AEM because of its features and I'm expecting ALLOT of trial & error during tuning. I'm planning on using most of the OEM fuel system with this ECU just to max out the OEM setup

I have a Haltech F9 on my lightly modded '88 Vert Turbo, and it runs pretty near as hard as my (stock) '97 FD....
If you want any info (and a great price) on Haltech visit RPM and drop Tim an email (I have no affiliation, but he looks after my cars VERY well and knows his onions!)

I don't think the AEM is even out yet. and it isn't plug and play for the FC. you need the race version that comes with it's own harness like the haltech. so either one you'd rip out all engine wires and ecu and replace. not an easy job. nobody has used the AEM since it's not even out yet. the Haltech is very proven and lots of surport and people who know how to use it. but get the e6k. I don't even now why you'd bother with the F9

The Haltech also has datalogging, and I don't know what is meant by the "systems integration" of the AEM, but to me it looks like every other EMS. Both have boost control, but the Haltech's is not very good, and the AEM's remains to be seen. No Plug & Play AEM for the FC right now, and I wouldn't hold my breath for one in the near future. Before you decide if new wiring is a downside, look under your hood again, and notice the nasty, greasy, cracked, 11-16 year old original wiring and corroded sensors that Mazda charges a fortune to replace - do you really want to use this on your baby?
My own opinion is that the AEM looks very good on paper, but the E6K has been proven to work. I haven't even seen the AEM for sale yet, so I guess that makes the choice easier.

How many extension boxes do you have to buy with Haltech again ??
I though Haltech required you have a laptop hooked up to get dataloging. My OEM wiring and sensors are pretty nice thank you Granted the "no shielding = weight savings" is pretty pathetic.
Its enough to make you want to go carbed/analog again

Can you name another EMS which does on-board datalogging?  The only ones I can think of is MoTeC and Wolf...

The MoTeC programming is a little bit more hard to decipher initially, but once you get used to the controls it's not too bad.
Minimum, a MoTeC M4 Pro will cost at least $2000 - almost twice as much as a Haltech E6K.  The MoTeC hardware is top-notch; all connections and wires are Mil-Spec.
