In my Alpha Sapphire game, I chose Treecko. I figured that Torchic and Mudkip would be a lot more common, and decided to go with the one that I thought was chosen the least. My Treecko, now a Sceptile, has definitely proven herself as a strong and valuable member of my team, and that Mega Evo never hurts either!
Oh and you got a female starter? Lucky, I always love getting female starters since they're so uncommon haha~
