Here is an article In defence of swap: common misconceptions by Chris Down from 2018. It has a "tl;dr" section with 7 points, if you just want have a quick look.

I setup a swap file instead a partition, it's just more flexible, but same concept. The swappiness settings cat /proc/sys/vm/swappiness is at "60" with a total size of 64 GiB on a very fast NVME SSD. If this was a slow HDD, then any writes and reads would be much more noticeably slow. I had it disabled in the past too and didn't notice any difference. The only difference to me would be, if the system RAM fills up, then the system could freeze and maybe crash. Or the system will unload applications to make room, and it could hit randomly an important app. Imagine a program has a memory leak.
