I think drums are hard because its more than just keeping time. Different styles are completely different vocabularies that require different dexterity to be effective. That said, I can pretty much play "rhythm everything"- meaning drums, bass, guitar, piano. Im not particularly good at any one instrument nor do I feel Im an expert to speak on any instrument but if I had to rank the instruments I can play in order of difficulty I would say: 1) piano - playing chords in a rhythm is not hard, separating your hands can be tough and playing classical can be infinitely difficult. 2) drums - I am not a natural drummer, so staying on rhythm and fills and different styles was a hard won battle for me. I think that some people are born with this ability so drums may seem simple to them. 3) guitar - probably the easiest instrument to compose a full song with, and its somewhat easy to vary from chords to leads and back. I think that anyone with 6 months and some determination can be a "competent" guitarist or at least get over the learning curve. 4) bass - I think this is easiest because you have the choice to relegate yourself to the rhythm section and just play a groove. Im sure that others may feel differently, and I don't think there is a right answer. Being a virtuoso at any of these instruments is truly difficult, but getting over the learning curve and playing for fun definitely varies.
