Should I Get a New Composite Filling or Veneer?

I chipped my front tooth when I was 18, and it was repaired with a composite filling, now 31 it's time to have it replaced. The last years I have been tired of the filling flaking + having visible edges (feel it easily with my tung as well). That makes me want to have a porcelain veener instead. But I am afraid I will be just as irritated with the edge between the gumline/real tooth and a veener. Will a skilled dentist fit the veneer so good that I can not see nor feel the edge of it by the gumline?
