Emerald Dream vs Rebirth Classic WoW Servers

[porigromus]

I have read good and bad about both servers. What are everyone's opinions? Is Emerald Dream really poorly developed compared to Rebirth? What is Rebirth's population like? I have tried Emerald Dream but not the latter. I haven't reached end level yet on Emerald Dream but everything seems okay, especially the population. I do notice a lot of lag though and some things are a little buggy.
