Actually the Ganzi favored class bonus for Oracles allows for both Cleric
and Wizard enchantment spells (although Oracles cast using the Cleric list anyway), but the Grippli FCB only allows Wizard enchantment spells (at a +1 spell level penalty), so it's not
quite the same.
It's also worth noting that FCBs that give +1 spell level penalty can be exploited by using even levels to swap a spell known for another spell known of the same spell level, thereby letting you get a stupid spell at a +1 level only to instantly swap it for an Oracle spell known at your highest spell level. In effect, that means that every time Oracles gain access to a new spell level, they instantly have 2 spells known of their highest spell level instead of 1, which is pretty good.
Otherwise the Shabti favored class bonus may be best, considering an Oracle has multiple methods to nab Wizard spells anyway and there may be some unusual pickups in the Psychic list. If the Oracle also chooses to get
Improved Eldritch Heritage (
Psychic) (This costs 3 feats, however.), it is also possible to get all the Psychic bloodline spells that can be undercast to auto-level to their highest spell level whenever the Oracle obtains a new spell level, which gives a neat synergy, especially with the above stunt of immediately swapping a spell known for the highest level Oracle spell known.
