I dont think any server is better then the other, but there are different aspects to each server. This is best done by checking the official forums at http://forums.lotro.com/forumdisplay.php?f=77 and reading the descriptions.
Depending on what you want in the game experience, my suggestions are Landroval if you like a heavy RP community. If you would like to join the Allakhazam community, then you would want to make a character on Meneldor, and look for "There is no fifth star" members to invite you.
Or...you could make a character on each server and test it out.
