I never claimed to beat xz as a general-purpose compressor. .tar.xz is the dominant format for Linux source tarballs and distro packages. So optimizing for ELF + x86_64 is optimizing for a very real and common case, not some toy benchmark.

btw goal of the project was not building a production ready solution. It was curious case of black box software development. Compression is great because input and output are precise bits. As for speed, I think it's comparable since it's using most of XZ infra anyways.
