The shape of the ear allows it to filter certain frequencies which help us figure out where a sound comes from. Computer headsets take advantage of this to trick your brain into thinking a sound is coming from front or behind depending on which frequencies are filtered out. Pointy ears might not be as good as this type of filtering and may be at a disadvantage at locating a sound (just guessing).

I would also guess that pointy ears might get a lot colder than rounded ears. Round ears can get pretty painful in cold weather. That pointy part that sticks out would be even harder to keep warm. That might also be a disadvantage.
