I was doing a damage / Def comparison. The Templar will most likely be a bit more defensive while the merc with a shield build a bit more of a DD. By "all around" I mean damage / Def balance comparison. I'm just not so certain a Templar is worth playing with the versatility of a merc. I think this is why there aren't many high +'ed 1h maces on the server because they are expensive and grant the user only an option for 1h damage no dual wield.
