Metal, because everyone is always crazy and makes really hard guitar parts and drum beats. Some really hard Guitar and Drum parts would have to be by Metallica!

Its ok that metal Rock Music needs more energy and hard guitar drums part. The drums part is really very intricate playing of beats. But One cannot say its the most dificult. Hard metal music has distortion effects which really over shadows the seriousness and importance of rendering the notes melodically and pin-pointedly accurate.

The importance of hitting or singing the accurate notes are very much taken care in Indian Classical Music and mid eastern(Persian, Arabic) genre of music. In Indian classical music, it takes an artist atleast 20 yrs to achieve such perfections in rendering accurate notes, fast modulations(gamak) fast note syllables(taan) impromptu, with proper voice culture(for vocal) and hand culture(instrumental) and rigorous practice.
