Zsawp is not Zram, which is a distant relative of the macOS on-the-fly compression I was talking about. Zram is buggy and still advised against regular use (https://news.ycombinator.com/item?id=38300432) on the fly. Zram is a compressed RAM block device with a hard capacity limit.
There is really no comparison here at this point. macOS is vastly superior in that regard.
zswap works well in my experience. Don't need both. Combined with systemd-oomd I haven't had a swapping or memory issue in many years. 16gb here with VMs and lots going on. This doc clears some things up:
