1999 here. The reason the cusp is a noticeable issue is that there's a clear microgeneration we've missed out. Just like 1977-1983 isn't quite X or Millennial, 1997-2003 isn't quite Millennial or Z.
Now as the 77-83 group call themselves the Oregon Trail generation after a popular game, we also need a similar name. We are the Club Penguin generation. Who's with me!
