I always choose Orcs, because I like being a fighting bastard. And yes, with the race perks the Nord would probably be a better choice for a fighter, but I just like Orcs. I have Tolkein, Warcraft, and an influential mind to thank for that. And I mean the books, and the first Warcraft. Besides, in Oblivion and Morrowind I managed to get enough skill in all areas to complete all the quests, including the Mage Guild with an Orc who had basic working knowledge of magic. Magic is fun, but nothing feels better than smashing in a skull with an axe.
