Personally I'd say Press the Attack + Rains (Fury) is the best option, since:
1. Being short-term outscaled and then attacked by this Gamer dude, possibly while the Apocryphal Curse 'procs' again so we get outnumbered or placed in a tactically disadvantageous situation is horrible and possibly fatal.
2. Rains is the option which maximizes our short term power and safety, by preventing death spirals and immediately resolving the current spiral.
a. It also heals Letrizia immediately, basically letting us have our cake as well as eating it. This healing is also guaranteed.
3. Requires no Arete expenditure, thus appealing to those who desire we save Arete and to then take a 7 Arete or 25 Arete option.
