I would say, yes, both are worthy to be upgraded. I just maxed my Ragnarok and I would say she's really useful in FAWs. Sophie is a decent crit attacker too, provided you don't have Scylla. (I'm assuming you are going for a full-passion deck)

Honestly, I wouldn't go for Unit Bonuses such as Goddess of Protection when it comes to building an AW/FAW deck. I would normally try to go for at least 2 AoE 200% buffers, Lilim, and 2 crit attackers. Unit Bonuses are only useful for Defence Deck (if you're into dueling) and Alliance Battle.
