If you want to see a comparison against an even broader set of open source compression algos, this is lzbench (it's linked directly from the ZXC github page)
lzbench has added ZXC to its suite. This makes a nice apples to apples comparison possible.

> Unlike symmetric codecs (LZ4), ZXC trades compression speed (build-time) for maximum decompression throughput (run-time).
Huh? This is exactly what lz4 does. Yes, zxc is faster than lz4 at decompressing, but lz4 is clearly asymmetric in the benchmarks shown further down on the page.

And afaik this is what most compression algorithms do. It’s certainly one of the trade offs you have to consider when archiving at high levels of compression.
