Kingdom Building -vs- Border Wars

As a player in “Age of Conan” you can take part in epic conflicts with full force, vying for the ultimate in dominance and power. In the area called the Border Kingdom -- situated outside the game’s three nations Cimmeria, Aquilonia and Stygia -- player guilds can fight for the right to control large battlekeeps. Once captured, players will have to defend their property against the ruthless attacks of other players, driven by both greed and envy. At the same time players can also build entire cities outside the Border Kingdom, which other players can not attack! You must however be prepared to defend them from sieges brought on by computer-controlled enemies hiving next to your city.

At first glance what appeals to you more? I must say at first glance now that I realize kingdom building is PvE I'm heavily leaning towards the more Dark Age of Camelot sounding Border Wars
