3850 Stack - Upgrade to Everest or Downgrade to Denali

We recently purchased 3 WS-C3850-48F-S switches that we are planning on stacking. Two of the switches came with 16.03.07 (Denali 16.3.7) installed while the third switch is on 16.06.05 (Everest 16.6.5).

In order to have all 3 switches in the stack running the same IOS image, should we downgrade the third switch from Everest to Denali, or upgrade the other two switches to Everest?
