As far as I can see they're both still "build your own" systems.
They look nice, and I have no doubt that they will produce the effects that I want, but I'm looking for a 100% pre-built solution. Something that is a complete boxed product that you simply unpack, plug in, and go.
I don't have anything against these build your own sets, but in all honestly I do not know how to read a wiring diagram, I do not understand half of the terminology that they are using, and I don't want to blow out my fuse box because I've soldered the wrong wire into the wrong place.
If the kit kit isn't per-built, then I'm simply not confident plugging it in. I don't trust my own ability to put it together.
