I went with AEM so I can drive the coils off of the ecu directly. I had a AEM v1 but would have had to run the coils at wasted spark. Nothing wrong with that but I wanted to run the ignition sequential spark. And its possible to hook up a cdi box in with this as well. I just ran the coils directly off the ecu.
There is a kit that you can run with Hondata S300v2 for "coil on plug". Have several friends that are looking into this style setup, which you have a extra box you have to wire in to get it all working.
