Sorry, but BS3 is so 2001. That box is seriously outdated.

The software was just updated this year for BS3 users and, again, BS3 has been able to control late model GM transmissions many years. It wasn't until about 5 years ago, that you could get a Holley Dominator which is able to do that. 2001 puts BS3 a good 10 years ahead of what Holley Dominator systems have just been able to match.

Megasquirt just released MS3-Pro Ultimate at PRI a few weeks ago. Holley efi must be outdated and so 2011 now

But none of those have the processor that the AEM does.
And BS3's claim to fame has been with the drag racing community largely because of it's datalogging capacity. Drivability however isn't as good as some of the others.

The Holley EFI systems have amazing data logging capabilities and drive awesome.

Not to discredit you or holley but it's mandated to run the holley hp as the only efi for use in pro stock, part number 554-129. It's a specific hp ecu and I can't find it for sale even on holley's website, probably have to buy it right from the nhra so they can get there markup on it.

I know you weren't quoting me but yes I do run a bs3 in my street/strip car, 16 injectors, lots of street time and e85 fueled for both street and track.
The bs3 is an excellent and easy to use main stream high end ecu with a better than oem harness and connector set. As Jon said it's only gotten better since the new software was release this past year.
I wouldn't discount it as being an excellent system to pick up used at a good value on the cheap.
Nothing wrong with a holley system as well, depending on one's needs the hp and dominator are both excellent values. Just be careful with that mini usb port, the holley ecu's are potted and can not be repaired.

My street car, 16 120lb injectors controlled by bs3.

No Andrew, I have a Megasquirt 2 I'm working on at the moment. It controls, fuel, timing and has some additional features like boost/nitrous control but I don't need the extras to build an efi system using TBI and HEI on my 4 speed Poncho. I had FAST XFI 2.0 but sold it because it was pretty much overkill for what I'm building and I wanted to build out my whole system. In my case I simply don't need Megasquirt 3, MS3-Pro, Holley Dominator, or the XFI 2.0 like I used to have. You've seen my stuff when I had the FAST and we've exchanged conversation on efi subjects on the Pro-Touring forum. My profile over there is F-Body International.

I used to glorify the Holley as well, but after going over efi topics with my friends and being on the forums, I have become less and less impressed by Holley efi. I'm not saying it's bad, but I've just become less impressed. In the end most efi systems generally do the same thing. You really have to know what you're talking about to say one is better than the other. I personally would rather have an ecu that is serviceable and also able to upgrade. For instance, with FAST, you can start with a base XFI unit and add traction control, logging, etc. With Holley you're stuck with what you have if you buy the HP/Terminator box and it can't be upgraded to the Dominator.

My Megasquirt MS2 carb-to-efi kit was around $600 and came in at about $750 once I added my Innovate LC-2 wideband setup...Black Friday sale at www.diyautotune.com

Bs3 seems to work pretty well for the world's fastest street car. I'm not saying there isn't a lot of great stuff available on the market today, but I would definitely say a used bs3 or fast xfi system can be a very good value.
If purchasing new I personally would take a good look at the haltech elite 2500 or the fueltech systems myself.
