I think that I personally prefer .net because I started on there 3 years ago, so I am already pretty advanced in the game, and I would have to start all over if I went to .org. Also as some of you were saying, I have quite a few friends that are on .net almost all the time.
I used to be full on "Org is the best" but now I think that Net and Org are both pretty good servers. You have strong points and weak points on both servers, and I think they equal out to each other. I like being a little greenie on Net because then I am actually playing a more challenging task, while on org I get to fly around and be able to make my island as intricate as possible. So Net and Org!
Org are where my friends are and what I have dedicated myself to. I do not have anything against either of the servers. I will admit that org does need at least a few more players. Sometimes I am one of the very few on the server.
org is nice and quiet, but there just isnt anybody to show off to. i like to show my creations off to the masses. (even though theyre never really that good but some people are easily impressed)
I prefer .org more than .net. I say this because, a). I actually have something to do and work on whenever I log in b). The community is chill af (though there can be little tiny arguments - funny af in my opinion). c). You could legit make friends with anyone, just by giving them a piece of cobble or paying them $0.69. d). Barely anyone feels left out since there's such a few amount of people on to the point where you could literally have a conversation with the whole server. .net is cool too though.
