1 Lagged / "Lazy" Queries - React Query provides a way to continue to see an existing query's data while the next query loads (similar to the same UX that suspense will soon provide natively). This is extremely important when writing pagination UIs or infinite loading UIs where you do not want to show a hard loading state whenever a new query is requested. Other libraries do not have this capability and render a hard loading state for the new query (unless it has been prefetched), while the new query loads.

2 Render Optimization - React Query has excellent rendering performance. It will only re-render your components when a query is updated. For example because it has new data, or to indicate it is fetching. React Query also batches updates together to make sure your application only re-renders once when multiple components are using the same query. If you are only interested in the data or error properties, you can reduce the number of renders even more by setting notifyOnStatusChange to false.

3 Partial query matching - Because React Query uses deterministic query key serialization, this allows you to manipulate variable groups of queries without having to know each individual query-key that you want to match, eg. you can refetch every query that starts with todos in its key, regardless of variables, or you can target specific queries with (or without) variables or nested properties, and even use a filter function to only match queries that pass your specific conditions.

4 Automatic Refetch after Mutation - For truly automatic refetching to happen after a mutation occurs, a schema is necessary (like the one graphQL provides) along with heuristics that help the library know how to identify individual entities and entities types in that schema.

5 Normalized Caching - React Query and SWR do not currently support automatic-normalized caching which describes storing entities in a flat architecture to avoid some high-level data duplication.
