The Microtech handset gives the same info as the Commander (except AFM voltage - for some strange reason )for a MUCH cheaper price! Then you've got the Dash on top of that. Microtech has basic logging via handset and full logging via laptop.
I've been very lucky that my choice of tuner and aftermarket ECU has saved me a great deal of money. I've had excellent tuning support and very reasonable prices throughout the whole ECU, handset, injector and tuning upgrades. Had I gone with the PFC I wouldn't even be close to reaching the point I'm at now.
The Microtech requires 1 additional sensor (inlet air temp) which takes bugger all time to install and wire, and by using the existing AFM wiring you have no need to run any wires at all. It doesn't actually NEED this sensor to run, but without it you aren't making the most of the ECU. Other than that, it's plug-in and away you go.
With the Microtech you're not locked into any particular injector type. High or low impedance is fine. This was a big saving for me! (workshop was able to use local injector suppliers MUCH cheaper than Japanese bolt-in stuff) AFAIK the PFC requires the OEM injector impedance, yes?
I guess where I'm going with all this is... there's so much more to it than JUST the brand/model of ECU that you chose. With a good tuner the LT12 (and I daresay all LT models) can be made to run fantastically, with excellent driveability, idle, cold start and economy only a touch below a closed loop system.
ANY aftermarket ECU can be made to look like a piece of crap if it isn't well tuned, or correctly suited to the application. And I firmly believe it is for this reason that many ECUs (in fact many products in general) get a poor reputation.
