Linked servers rating?
Unfortunately I think this is highly unlikely. In the eyes of Anet “guest” servers (the ones that are linked) are nothing more than a way to vary the match ups for the “host” servers.
If you are a beginner the question you really need to ask is “Which server has the most welcoming community?”. You should look for a server with some experienced players who are happy to welcome you and will share their knowledge. You will also find some form of voice comms (teamspeak, mumble or discord) to be very helpful.
