RoA is typically better, because it gives you enough mana anyway and the same amount of health as Rylai, but with stronger early laning bonuses from catalyst.

However, Tear+Giant -> AA+Rylai later is definitely not bad and I would even recommend it if the enemy team is very prone to kiting (Udyr top and Shyvana jungle or sth like that)
