What better RaidCall , Teamspeak or Discord?

More than once I have asked myself the question , what is better to communicate with somename in the game. And was still on RaidCall all the famous ... but the very existence of better communication haunts me .
Yes , RaidCall is good in his usual easy and suurennettu (although it is possible that other forms of communication I know is bad). But poor quality when compared to the same Teamspeak and Discord , but Discord noticeable girl large live an Internet and if the person has problems with the Internet , his ISP , and the game begins to notice that just stupidly does not pull inet, and it is in this whole issue ...
What do those people who have the Internet can't pull a killing moon and the game to poiotita to stay on RaidCall , because he eats much less . The other side of the coin , this is Teamspeak and I, as head of the clan , want to find a network for their Baklanov to transfer mwasi was the norm and the Internet ate medium and Teamspeak here is what you need , but he paid . Should I pay for a server for my clan (and so to win it every month )... Yes , damn it , like the free server but this is , frankly , kind of bullshit . Tried to deal with it, but never found the answer to your question : WHAT connections GO ?
Advise something , maybe someone knows another good network that will work for me . And about the teamspeak I will be grateful , if help to deal with free server.
