At a glance, I see three additional features. First, there are two complete Spike-equivalent relay pairs in each module. While we've never quite run out of 20 amp power distribution circuits, this would have helped us stay comfortable. Second, there is a distinct power indicator light, which is a welcome addition for making sure the electrical wiring is okay. Third, and most interesting to me, there is a specific power return connection along with the two relay-controlled outputs. That last one makes it much more convenient to wire pneumatic solenoids or custom light circuits or other things that can be run from one half of a Spike.
Using screw terminals instead of fast-on style connections is a difference that I expect some people would consider a feature as well.
