Use the scroll event since that's the actual event that is dispatched when the scroll position changes. The wheel event is dispatched when the scroll wheel moves, but that is not a perfect correlation with scrolling; the scroll wheel is also used for zooming (zooming by pinching with the trackpad dispatches wheel events with ctrlKey set to true), and the page can be scrolled without using the scroll wheel (using a finger, arrow keys, tab key, URL fragments, and Windows smooth scrolling)
