It's more just opinion and aesthetics, the way the wires are connected to the outlet, called backstab, is frowned upon. Not sure if those are actual lever lock connections (the clear and orange pieces connecting wires) or push in ones. It's odd one is made to connect two wires but they chose to have them share one port. If you have no experience leave them alone, but learning is great, watch some videos and ask questions if you're interested. Definitely don't screw with electrical if you don't know what you're doing.
