Decompressing xz is supported by busybox and internally by busybox tar
and gnu tar, so I don't see any practical risk of the user not having
support. On the other hand, nobody has ever heard of lzip or clzip and
they're certainly not supported in the widely available tools.

For a compression format (from the perspective of the party doing the
decompression), the only technical details that are relevant are the
compression ratios and the memory and time requirements for
decompressing.
