Yes, you should consider using async streams for Combine when dealing with asynchronous sequences. Async streams can make your UI feel more responsive by streaming results as they become available, similar to an async sequence. This approach is particularly useful when you want to reflect the first result in your UI right away, rather than waiting for all results to be ready.

For example, in the session Meet the Translation API, it is mentioned that streaming results as they become available can make your UI more responsive. This is akin to using async sequences in Swift, which can be efficiently managed using async streams in Combine.

Additionally, the session Explore Swift performance discusses how async functions are implemented and managed in Swift, which can provide further insights into how async streams can be beneficial for performance and responsiveness in your applications.
