Just why would you go there?
There are already tons of legit and completely known sites so why going on a newcomer if there isn't any new feature?
Maybe he was invited by someone and got curious thats why he is asking for other opinions for legitimacy of this sites,or maybe OP is just bringing the sites up for some other reason
But the thing is you are right that there are tons of existing sites with good reputation (if not really perfect)that can offer happy playing without risking of being scammed or victimized
