I don't think you can really highlight one aspect over another in this way as they are serving different purposes, which will effect newer and older players differently or have benefits that range between short term and long term etc.
When designing a server it is important to do so around a main hook which will set the server apart, but eventually you need to look at the cumulative effect of all it's different aspects and decide whether there's enough balance, in order to satisfy as many different types of player as possible.
