a zero crossing detector is much the same as [>~] followed by [rzero~ 1].
Therefore, first it does a destruction on the signal as harsh as the
harshest fuzz with the highest possible gain. This removes most timbral
features of the signal and boosts some others by the maximum possible
amount, in a way that isn't perceptual at all (e.g. it's very
DC-sensitive, among other things).
I don't know why anyone recommends zero-crossing detection. But if it's
after some kind of [rzero~ 1], that already makes more sense, but that
detects the positive and negative peaks instead. If you use [hip~] before
[>~] instead, it will pick something intermediate to those.
