RoA is cost effective even without any stacks, and is one of the most cost effective items in the game @ max stacks. It gives you all the health and mana that you need, in one slot along with some nice AP. AA gives more AP, but no lane sustain and no health. Rylais is unnesecary (wall is a huge slow, and it only gives health and AP).

RoA> AA
