Bows and Arrows. As said in one of your previous questions (keep them up, they're good fun!), being nice and far away and killing foes without being suspected is nice. Melee combat isn't all that interesting because of the little strategy required for the most part, but marksmanship adds a lot of tension to being discovered, and the kills are rewarding.
M. T Dremer said it right though about most of Skyrim's locations being claustrophobic and tightyly packed. The game's dungeons were made for melee, as easily proven by the narrow walls and small spaces to roam around. Plus if you notice most magic isn't in the form of a magic bolt but a short range channelled lance, furthering the question of if this game really was intended for ranged use. Archery is fantastic in the open world, but obviously not so much in cities, caves or anywhere that isn't instanced.
