Oly 12f2 or Oly 17f1.8?

help me decide.

my main use will be for travel photography and indoor shots for kids parties and events.

i'm leaning towards the 12f2 as it will give me the best flexibility. it will easier to move forward than move backward when taking the pics, right?

but which one has the best IQ? sharpness?

thanks for your inputs.
