Zswap is arguably better. It confers most of the benefits of zram swap, plus being able to evict to non-RAM if cache becomes more important or if the situation is dire. The only times I use zram are when all I have to work with for storage is MMC, which is too slow and fragile to be written to unless absolutely necessary.
