" Giant's Belt and Crystalline Flask serve you better for HP sustain though,"

I get that Rylai's is a better late game / post laning phase than RoA. I give you that entirely. The reason why I still think Catalyst is a better buy than Belt & Flask is that it gets you closer to finishing an item than Belt & Flask and eventually nets you more mana for AA.

Sitting on unfinished (worse, basic tier) items for a long part of the game is really gold inefficient.
