so, little summary as requested by some people.
what do i see here for myself:
1. in terms of size - lrzip in zpaq mode is winner but takes x3 time with default zpaq mode, and x6 time with maximum compression.
2. in terms of speed - zstd is absolute winner, with default mode it's not only faster, but also providing higher compression ratio than gzip and bzip with highest settings.
3. in terms of both compression ratio and sped - in most cases zstd -10 is good choice, looks most balanced, if you need high compression but with reasonable time, you can choose lrzip with default settings (in lzma mode high compression level does not affect compression ratio much), or lrzip with no compression + zstd compression, both provide comparable speed and compression ratio
