Both the Roku 2 and the Roku Streaming Stick use WiFi, so you don't have to plug them physically into your router. The stick plugs directly to an HDMI port on the back of the TV (so concealed) and then needs power (either via USB on TV or USB cord to an outlet with provided plug) so technically it would be one less wire since you would need a longer HDMI cable for the Roku 2. Both work equally as well, the Roku 2 may be a little faster connecting though. I have both and use a stick for the smaller TV in the bedroom and a Roku 2 on the main tv with entertainment center.
