Uppy vs Tus. Which one to choose?

Earlier I used to use Tus server but now I can see Uppy is also there. So which one to use? Which is better in terms of performance, scalability, functionality and ease of use?

Tus a protocol for resumable uploads. Uppy is an agnostic uploader which can upload using that protocol. You can use uppy and tus, your backend, or aws.
