Quick battle, do the missions mannually, Which one is better?

Question

I found that my rewards for quick battle are a bit less than my manual battle. Should I always do the missions manually?

Answer

Yup , quick battle always less reward

Answer

There is a display bug where if you quick battle twice, the second time will show the items you received from the first quick battle, but you will actually receive a legitimate reward worth of items. The game just does not properly display what you received.
Actually, quick battle will reset the reward tier you received last time and give you the same reward as if you manually cleared the same tier.
