I highly recommend getting either game, especially if you have a GO account to connect with for bonuses in game.
This game fixes many of the flaws of Gen I, such as wild Pokémon rosters, proper level scale, overworld encounters, farmable items, better TM selection, and Gym Leaders and Elite Four members with actually good teams. This game has references to SM and Megas as well.
There are certain trades and Pokémon exclusive to a single version.
Also, note there is an in game optional gift of a certain Pokémon that may or may not be version exclusive. Arcanine or Persian. Make sure you get the Pokémon that is not in your version. If LGP, get Persian. If LGE, get Arcanine.
