hstar
hstar is a command-line tool like tar, with several more features.
Use
To generate bash shell completions:
hstar --bash-completion-script hstar
Features
Unlike other tar implementations, hstar has the sanitize subcommand which converts a file into a pax-compatible archive and the lint subcommand which points out suspicious archives.
hstar can change the compression based on command-line flags, like bsdtar and arc (this feature is missing from GNU tar, busybox tar, and seemingly Schily tar).
Compression
hstar has near-parity with other command-line tar implementations with respect to compression support.

Performance
Benchmarks run on Linux. Performance should be near GNU tar, bsdtar, or Schily tar.
