I have played RO, on and off, since it was first released in 2002. In that time, I have bounced around multiple fan servers before landing on HeRO in 2012. The biggest selling point of this server is its effort to add features that have become commonplace in modern MMOs; things like fishing, mining and an allegiance system. Plus, while popular fan server trappings like Warp NPCs exist here, they must first be earned through questing. All in all, it is a version of RO that is second to none.
