people flock to UN because there are many people on UN, it has pretty good levels and weapons along with skills, however I define a server as good by truly unique scripting and features. With many interseting GFX and levels. Teamwork is something that is missing from many servers, though I have seen some servers with it. I personally think the best clasic and non-dev server...(heh because if it were dev, I would say Dark Rival, obvious reasons

)...is maloria, because they fit many of these features. There are problems with all servers though. That's why I'm glad I own my own server, because I can make it perfect
