For desktops, zram with no swapping to disk. Hasn’t given me any trouble yet, except for the rare news website (it’s always news websites) with a horrific memory leak.

For laptops, zram plus a low-priority swap file for suspend-then-hibernate. My old laptop drains a fair bit in sleep mode and my new one doesn’t have proper S3 suspend because microslop is pushing manufacturers to only support S0 idle.

Always a file, never a swap partition. Everything that can be encrypted lives inside the encrypted root partition.
