Faucets I do not recommend at any level. Just hours for cents worth of pay which is not very good. Signature campaigns at full member and above will beat faucets by a surprising amount.
Also with signature campaign if done right you are doing your normal posting nothing special. So you get paid to do something you would do anyway's which is pretty great. Used right signature campaigns are the best "free" way of earning.
That being said my favorite will always remain mining. I just enjoy it and it's a lot of fun.
but we can not underestimate it
faucet has helped many people to be more interesting to bitcoin
and the faucet had a role to advertise bitcoin
and who introduced me to a bitcoin is faucet
