The two Qi chargers I've used don't really require much lining up. With the Pixel Stand the alignment is obvious, I've never missed the alignment on that. I also have used Samsung's round, flat charger. Its a circle. Its hard to miss the center of the circle.
The Qi wireless charger for my Galaxy S5 has a noticeable precision requirement for placing the phone - it doesn't charge at full speed unless the phone is accurately placed, which is infuriating and makes me cut back my use of wireless charging; I've confirmed this by having a USB power meter attached and watching the current draw change as I move the phone around the pad.
That's why I stopped using a wireless charger.
