Does delay/attack speed affect aggro retention?

At low lvl it is going to depend on the actual weapon options you have available.

The combinations are numerous enough that you probably should just parse your own data and find out what has the highest white damage, and experiment with different combinations in different situations (high dps grp member, high mr mobs, etc.) for what you can consistently hold aggro with best.

In general, all other things being equal (procs, level, mob, etc.) the faster swings will probably be better to hold aggro...but it depends on the actual weapons.
