I wouldn't say I have a preference because I like to experiment with various builds. Currently I'm working on a Nord Mercenary. He uses One-Handed, Light Armor, Block, Archery, Pickpocket, Lockpicking, Sneak, Smithing, Enchanting, and Alchemy. My goal is to get him to level 81. I'm only taking a few perks in Pickpocket, Lockpicking, and Sneak. Sorta like a Conan build.
