I don't know how it is recently as I performed this test a few months back but I was able to acquire about $6 from btc faucets in a hour. I had to do a little work firstly as I compiled a list of working faucets and preloaded them in the browser then went to town filling them out.  It's worth noting not all the faucets paid as most have a minimum requirement for withdrawal but I still included the reward in the total.  It was mindless work and required to be extra careful on captcha's. I also run a faucet and can say a lot of people use faucets on a daily basis it must be worthwhile enough to them to continue to do so.
