Choosing Resonator for AtMega328P design?

The ATMega328P datasheet specifies a load capacitance for a resonator from 12-22pF but the only 2 Resonators that will fit in my design (from Digikey) have 10pF and 33pF internal capacitors. Which one should I use, the 10pF or the 33pF, and what are the tradeoffs?

Here is the atmega328p datesheet

AFAIK the capacitor should match whatever the datasheet of the resonator states.
The atmega datasheet is for the reference design and I doubt you will have any negative effects by matching the capacitor to the crystal instad of matching it to Atmel specs.
