I'm not really sure. I mena if their both basically the same does it matter? you can get both Lugia and Ho-Oh. I think that it just depends on prefernce this time. If I remember correctly when the originally came out you couldn't catch both Lugia and Ho-Oh only the legendary according to your version. Now that they have basically broken down that barrier I dont think it makes a difference. Now it comes down to the real life trouneys and special event pokémon.
