I would splice a new receptacle box from that circuit (assuming the circuit is not filled with the max allowable boxes) at a location that makes sense for where you are installing it (I'm not a big fan of the long term use of extension cords). I think you'll find that the remote is 'line of sight' so factor that into the location of the receptacle box.
Personally, I would install the lighting first, getting it exactly the way I wanted it (using an extension cord to test it). Once that was done - I'd install the receptacle box to where it wanted to plug in - does that make sense?
As to which system - that's up to you - they both have reviews - one talks about off colors - that would annoy me.
