I've had a Core 2 Duo with 3GiB of RAM as my daily driver for years. I originally used zram, and saw some benefits from it, but when I switched to zswap the benefit can only be described as magical.
My understanding is that the rule of thumb is "zswap if you can have a swap partition, zram if you can't". Slow writes like you'd have on eMMC/SD might tip the balance in zram's favor, though; every machine I've used zswap on (including my PBP) has had a fast SSD to back it.
