I definitely prefer the AA builds over the ability builds. There's already so much to manage, and honestly, jump is damn near useless. If an enemy is on you, and thats your only escape, youre going to die anyhow. So, doing more dmg and being able to camp and get xp for the team, thats the way to play vikings. Though, in the same vein as that thought, Burning Olaf is better IMO for taking camps, and also doing sneaky aoe dmg to enemies during teamfights.
