My opinion that altcoin faucets isn't beeter than bitcoin faucets. Why? Because altcoin faucets isn't very popular, it means that owners earn less profit than from bitcoin faucets, so they can't pay bigger rewards. Only doge and litecoin faucets are a bit popular, but value of these coins are stable, so you can't earn a lot from it in long period. What about smaller coins - it's very hard to find faucets for such coins. Ethereum is very popular, but there are only few faucets for this coin, and less popular coins almost don't have faucets.
Yes, as I can see, is better to buy alts with bitcoin or something like that...
Giveaways is cool too... Anyone using altcoins signatures over here?
