Um.. no. Read my post well. I said that if he/she is planning on getting XD, then LeafGreen is a better option because it has the Slowpoke family. The ONLY Pokémon they won't be able to get in XD, besides the Kanto Starters and the Fossils.
Then I said that if he/she had RS, then FireRed was a much better option because it had more Pokémon you can't get in Ruby or Sapphire. Want proof?
