One thing that drove me crazy about using Apollo for local state management is that you have to manually fetch, update and save the data on every change. For example, if you have a list of items and you need to add one, your mutation would need to query the store for the list, add your new item, and them write the mutation to the store.

This adds extra overhead on every single mutation as opposed to Redux, where your the current state is automatically passed into your reducer, and you don't need to worry about writing anything after you update - the store handles that itself by updating the state to the result of the reducer.
