It's fair to note that while both offer AP and mana sustain ROA takes longer to start stacking and requires more gold to be spent up front, keeping you from buying very necessary items like boots. Also the shield from Seraph's, along with Barrier, Heal, or Exhaust; allows Cass to survive very heavy burst. Generally if Cass can survive burst she'll win a fight because her DPS is so strong.

Both items are very strong on her though, play to your own style.
