I prefer using dadice.com
The site is nice and clean, you get more payout on faucets the more you play (loyality bonus) which is pretty cool Its my favourite dice site after I saw it. Plus you get a reasonable payout for reffering other people to play on the site.
They also have a sig campaign running which makes them even more trustworthy

This is my honest opinion, I am not trying to advertise by purpose.
