I want to ask a very simple qu

I want to ask a very simple question but I wasnt able to find an answer online. I’m from Europe and play on NA Aion, should I choose a node closer to me or to the server or both with the advanced mode ?

You don’t have to choose a server where at the game server except the game has been region restricted

But when I use a node closer to the server my ping is a lot lower than when I use a node closer to me ?

It depends
