Ingenuity II lowers the level of the synth, increasing quality for any recipe that is higher than you (1 star or higher)

Innovation adds 50% of your base control, not including Inner Quiet stacks, so it's essentially 2½ more stacks on IQ.

1-3 stars Ingenuity II will give you a bigger boost, 4 stars and anything below 1 star Innovation wins out. Also, good condition is better than either of them at any level.
