Again, Awful. I find it awful. Horrible way to play FPS games. Especially half life. When it was converted to controller they even changed the levels to make it easier to do several things.
But that is just like, my opinion, which is why I wrote it. Do whatever you like.
Ever played it in VR? That section at the beginning is quite the sea sickness! Even though it too is horrible in its own way, its fun.
