I think most people would agree that Shield of Norrath and Temerity have different styles and different goals, but mostly it is a matter of degree and style than substance.
Almost all EQ players have advancement as a goal. The only players I can think of who don't are the ones who open up bread shops in Norrath cities with their level 1 toons and basically never enter a dangerous area. And there is nothing wrong with this, though I cannot say I have seen anyone this hardcore roleplaying on Al'Kabor.
All EQ players have fun as a goal. The only issue is do you want to have fun killing the biggest things available or do you want to explore and kill all the challenging areas in the game.
Shield of Norrath definitely has advancement as a goal. It just isn't a goal we plan on spending 5 nights out of 7 raiding to get. There are a lot of people who like raiding 5 nights out of 7 and there is a place for them, Temerity. Temerity has done very well advancing through the game, and I might add negotiating the political hurricanes that have engulfed our small population from time to time.
Shield of Norrath will probably always invite people from other guilds on our raids. Whether or not anyone agrees on how 'pure' a kill was or whether it 'counts' doesn't matter, but for the record, no chickens were harmed in our Gorenaire kill.
The 'rules' are there to make sure you don't invite a Time-equipped friend to your Kael-equipped guild raid, not to be a rules lawyer.
Shield of Norrath commonly refers to itself as 'a guild that raids' rather than a 'raiding guild'. Whatever term you use, I think SoN has qualified for it since taking down Naggy and Vox, and we are no less of a raiding guild than DC and Temerity, the only difference is the pace at which we do it.
