If you're going for OP, Orc. HA, both weapon skills, Smithing, AND Enchanting? There's a reason I don't usually play them. Just for S&G, I once built one for maximum Tankage, maxed HA, Smith, Block, Enchant, Alteration and 1H. Capped Armor, and Dragonhide reduced all damage to 5%, then you can turtle for nigh invulnerability, stacked up the Atronach Stone/Perk, Magic, and Elemental Resistances so that only a trickle got through that wasn't absorbed, then hit Beserker Rush, and just stood there laughing. He Walked through Forelhost, didn't kill anything except the Wight Lord you need to get the key from, just let them pound on me, and yawned. (Otar, Shield of Ysgramor, and the rest self enchanted Daedric.)
Imperial, and Nord are also good Meleers, but I usually use Redguard for a Spellsword, or all around character. While not as OP as BR, Adrenaline Rush is real nice for sprining from the North Gate of Riften to Shor's Stone in 1 minute (Unarmored, or with your armor canceled by the Steed/Conditioning.) It'll also power attacks, Eagle Eye, Bashing, or whatever else you use Stamina for. The new additions of Alteration, and Destruction along with the best 1handed in the game make then the best Spellblades, even better than Dunmer IMNSHO.
