It's easily Sora. I see a ton of non-gamers wearing Kingdom Hearts merch, most of which features Sora. I don't really know any non-gamers who care about Pokemon for anything but the Pokemon.
Also, to answer your question, I think Marth or Ike warranted a spot on the list far more than Lloyd, and I say that with Lloyd high on my list of favorite gaming characters and Symphonia my in my top four games of all time.
