For Linux on desktop, my experience with swap used to be extremely bad before systemd-oomd. I got those system lockups easily in various workloads that for the longest time I went without swap, and a crashing program was a better experience. On the server, sprinkling in a bit of swap was standard practice in some orgs. As under load I could still log into a slow server and do something about it. My current problem with swap in Linux is that they make bad default choices. While a swapfile isn't optimal, allocating a slice of the disk for swap complicates my life when I do ram upgrades. Hibernate being tied to configured swap on a slice of disk (ugh), I just didn't even bother with it since upgrading ram.
