Led is cheaper, laser is older tech, most of the times laser is better but these days you really can't tell the difference for normal use.
Since my brothers always worked for a loooooooong time I would go for the wired one. Why? WiFi security tends to change every few years (wep, wpa, wpa2psk, wpa3) and if your device can't communicate with your new access point.... Well, that sucks ass. With the wired one you have that backup plan.
Edit: and to reinforce my own advice : which one is the most expensive? Buy that one.
