I had a dock and replaced it with wireless charger as soon as they were available. The ease of just placing your phone on a surface vs. lining up your phone with the dock is well worth it.
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.
