When I was new to bitcoin, I went on all the faucets I could find before I stopped and realized that they were a waste of time. The best way to get free bitcoin is to probably head over to the games and rounds section the this forum, many giveaways there. 
Faucets are a waste of time but it looks like he knows that. There aren't many decent giveaways in Games & Rounds where you have a good shot of winning but you can get 0.5mbtc from the 777 giveaway thread daily: https://bitcointalk.org/index.php?topic=254871.0
