Operators tend to dislike anything that is different from what they are use to. If you want to know if a particular control setup is better than another, you need to take some experienced operators and let them get a couple hundred hours using the controls, and then ask their opinion (also monitor productivity and safety).

The toughest part of using these newfangled (I haven't driven a lift truck in quite a few years) controls, is if your operators must operate several different pieces of equipment all with different control systems. From that perspective, you are better off trying to stick with similar control systems on all equipment, even if the control system is inferior to others available.
