For learning net gaining (peaceful play) I recommend LaF, Omega, Evolution, MD, LCN, Monsters, or NA (tagged as "Sodium" this reset). Of those, I only have firsthand experience with LaF, and they have some fantastic teachers in the alliance.
For warring, there are two premiere alliances. SoF and SOL. Neither are fighting this reset, but they usually do. I have firsthand experience playing with SoF and can tell you they are not only great at teaching you how to build a good war country, but also have fantastic organization and strategizing within the alliance so that your war country gets used to it's full potential (if you put the time in)
Message members of the tags in game, or just respond to the offers that are sure to be posted in this thread ;)
One more note: The alliance server has become a twisted perversion of what this game once was. I still recommend you play it because there are some great teachers in the alliances who will help you learn the game. But once you've learned, try the Primary server for more of a taste of how this game was originally intended. Far more competitive.. you're on your own there, but so is everybody else.
Good luck and have fun! And if you do have fun, please tell your friends!
