It depends on your playstyle. I rather have +200 mana and 20-30 AP instead of a mere 500 health, as I prefer to play her as an assassin. Her own heal (and usually WotA) makes up for the lack of health and the shield is a good addition in situations where you don't want to directly activate Zhonya's.

Additionally, Seraph's will continue to regenerate mana throughout the game whereas RoA won't once you've reached max stacks. I know that this is a vague argument due to her E, but it allows her to not directly aim for the next minion wave or base to reg mana. :)

The reason why I go for RoA on toplane is, because I will usually face more resistant enemies there, hence it helps me survive and, as you said, offers important stats with one item. However, it will then be my substitute for WotA, not for Seraph's.
