I don't know how hard he is to beat, you'd have to ask Pain or Itachi.
ot: On a more serious note, yes Kakashi is very hard to beat. However, he's going blind so he'll lose kamui. But nonetheless, he is still a very well-versed shinobi and has much knowledge. He gains alot of experience from his battles and is a good analyst. He's done a good job as a shinobi. =D
