I'm going to get both, though I plan on starting Alpha Sapphire first. In the past, I used to agonize over which version of a new Pokémon pair to get, but I've realized over the years that I'll ultimately want to get both versions, so I might as well save myself the time and effort and just admit now that I'll end up buying both of them. As for my Sapphire preference, blue is my favorite color, Sapphire is my birthstone, and Sapphire was my main game back in Hoenn's original release, so Alpha Sapphire seems like a natural preference.
