Pros: Cheap, feels solid (metal bracket) and the powder coating isn't bad. Good packaging. Cons: There's an extra crease at the top of the back that causes the whole thing to lean forward and partially blocks a USB port. If the bend didn't go that far and you remove the valve on the back of the derailleur, this might work. Ugly: Heat dissipation is marketing bullshit because it's the switch that generates the heat and the hole is at the top so the other style doesn't trap the heat.
