I don't think there's a single method that is optimal for all people. For example, I think there's an inflection point in your optimal strategy when your tasks pass the point where you can actually do all of them. For myself, I like to reframe the issue. Instead of "Look at all my tasks, which one is highest priority?", which takes lots of mental energy, I just concentrate on NOT doing things that don't support my goals. This allows me to tackle small chunks and build momentum. One of the best ways to get something done is to NOT do things that don't contribute.
