... why would anyone use this when now days there may faucets giving 1000 satoshi and its better to have 1000 satoshi every hour then 100 after every 5min.
The latter is indeed better (for users), however, I think when you own a faucet, you should create as much traffic (and therefore views) to your website, as this will increase your income from advertisements. Also, when people have to fill in a CAPTCHA to earn some Satoshi, this is a way to generate money for the owner of a faucet.
In the end, the owner of a faucet should create a profitable trade-off between costs and income; providing bigger payouts will result in higher costs.
