There is no question that FreeBitco.in is still the king and the world's largest and most popular Bitcoin faucet. It has over 60 million visitors monthly (according to similarweb.com) and almost 50 million registered users, which is far more than its competition. However, I think that FreeBitco.in is not only a good faucet, but also a great place for new Bitcoin users to learn more about Bitcoin. I believe the purpose of the faucet goes beyond generating revenue; it also serves to educate people about digital currencies, to showcase Bitcoin's usefulness, and to encourage adoption.
Also FreeBitco.in is a big casino and has very long history in this industry. Also FUN token will bring more users to FreeBitco.in because one of use cases of FUN token is gambling on FreeBitco.in.
Faucets gave away big amount in the past but as long as Bitcoin and crypto market grows more, the amount from faucets have to reduce. It is fair and reasonable enough. Because the core reason of faucets is to bring a coin to the crowd, to make exposure and to help them getting experience from free coins received from faucets.
FreeBitco.in does this mission very good in many years.
