They're quite close but I prefer Doge more ^{[both of them will do fine]}.

Not particularly better than them but you might want to also consider Tron, Ripple, Dash and Monero ^{[I haven't seen a lot of these faucets lately]}.

In addition to FinneysTrueVision's comment, you can organize an automated competition ^{[that chooses winners at random]} that requires users to promote your faucet on their social media accounts for a certain reward if they'll be selected by the automated software.
^{- I've seen some YouTubers doing this in the past but I'm not sure about the software names so perhaps you should do more research on this matter.}
