I can't really speak to which one is better since I rarely even look at faucets anymore, they're not worth the time it takes to enter the captcha since payouts went down after BTC broke $1000... but I do like the fact that Coinbox at least gives you a list of faucets right on its home page.
I think I DO have to use CoinBox (Payout lower than Microwallet and has a variety of sites).
Also, I agree that today's faucets are pure crap...
I had to type ~60 captchas in one day!
LandOfBitcoin.com is the only real site in my opinion that has a faucet suitable for me (All you need to do is "WAIT")...
