Attack damage is almost certainly going to be better first.

See, let me give you some numbers:

At level 10 you'll have 0.93 attack speed. A Recurve Bow will give you 40% more attack speed for a total of 1.196 attack speed, an actual increase of around 29% DPS for 1040 gold. You'll have 76 attack damage at level 10, and a Pickaxe with give you 25 more attack damage. The actual DPS increase will be around 33% for 975 gold. The attack damage item B.F. Sword is even more gold-efficient than a Pickaxe. Obviously, attack damage is a better choice for your money initially in damage value.

The benefit of hitting Bio-Arcane Barrage's damage faster is certainly worth considering, but its benefit is muddled by how autoattacking more pisses off the enemy minions more toward you more and attack speed's benefit is unlikely to maximize with moving to chase or kite. Lastly, Living Artillery gains more damage from bonus attack damage.

Of course, this is just in the DPS area. If you want movement speed, there's Zeal and Phantom Dancer while attack damage has no comparable options for that.
