In addition to what has already been mentioned, relating directly to the subject, 'most difficult level' will arguably always narrow down to Electrodynamix and the demon levels. I believe I share the popular opinion of Deadlocked being the most difficult level, naturally, because it was made with a higher level of experience, and with the latest features that together form difficult sequences, notably those wave sequences and moving objects.

As you can see, difficulty is somewhat measurable and therefore predictable compared to sole preference, which is why the Top 10 Lists all focus on preference as aresult.
