I've used both. The upside to going with the Dominator, other than the extra I/O's, is DBW support, transmission control, and dual widebands.
The HP ecu is just as powerful, but doesn't have some of the fancy stuff, so if you don't need that, stick with the HP.
I've run the HP ecu on a twin turbo small block with water/meth injection since it covered all my I/O's that I needed. Admittedly, something like that would be nice to have dual widebands, but it wasn't worth the additional cost just for that feature.
