Daily bit coins has been the king for a long time, but all faucet amounts are almost too low to even be close to worth your time.
BitVisitor! has seen its payouts drastically cut recently.
Right now, I am mostly hitting BitCoinGet for BTC. You don't have to register (you have to register at CoinAd) and it pays out 5000 satoshi, five times the base award of DailyBitCoins for watching a video. Plus you can do tasks. You'll never get rich, but it is BTC.
If you like chatting, Coinchat pays decent, but there is a 20% withdrawal fee, a few trolls, and you have to wait to "prove" yourself before getting the system generated payouts.
