What fires first PlayerAdded or PlayersService.ChildAdded?

The title says it all but what fires first logically PlayerAdded or PlayersService.ChildAdded

Here's a script for you to test it out:

game.Players.PlayerAdded:Connect(function()
	print(tick())
end)

And in a separate script do:

game.Players.ChildAdded:Connect(function()
	print(tick())
end)
