The short response to this is it depends on what type of squatting you're doing. Each shoe has its purpose. The long response is that certain things, most notably long femurs and narrower stances (but also including ankle mobility and other body proportions), affect your center of gravity when you squat. If, using your preferred stance, you find it hard to keep pressure through your heels while reaching depth without falling over backwards, then lifting shoes can be a great help. If you have little-man levers, it doesn't matter as much, and if you squat wide, the chuck is preferable.
