Lets just say this...like many of the 4Ed versions of races I liked to play in earlier editions, they don't have the same flavor to me, at least in part due to 4Ed's design decision of serving balance first. They don't fit with my internal concept of what they should be.
As an example, starting Dragonborn or Minotaurs are no stronger than an Orc- something that simply leaves a bad taste in my mouth. I understand why it was done, but I don't agree that it should have been. Githzerai, preternaturally dexterous in previous editions, are toned down to match other dexterous races from the PHB.
And lets leave it at that.
