I always preferred Wilbur's Chocolate to Hershey's Chocolate, but I also think that the taste of Hershey's got noticeably worse in the mid-2000s when they went away from cocoa butter to vegetable oil.
Closing the factories in Hershey and an attempt by board members to sell the company out from under the Dauphin County Orphans' and the Hershey Trust also soured the taste of their products for me as well.
