Apparently zswap is better for systems with more RAM and zram is better for systems with very little. If you don't know the difference this is what they are.
Zram is just a block device made from ram, like a ram disk, but it's compressed. So if you then set that block device as your swap file, then you are compressing the least frequently used RAM.
Zswap is like a swap in front of your swap, like a layered swap rather than a general purpose block device. So it's a little more integrated to the problem and does some memory management itself. But apparently its own memory management logic isn't useful below a certain scale of giving memory to it.
