Hive Guard are late creations in the planetary invasion scale.
Generally speaking.
This is another reason I try not to use them too much, as I'm more of a fluff thinker when I make a list. Hive Guard not only are created later in the invasion, they're made for one purpose - to defend capillary towers and digestion pools. They wouldn't be accompanying a Tyranid wave on the march. I guess they fit in objective games - you could very well have capillary towers as objectives. But generally speaking, they wouldn't be walking around with an attack wave. They're a purely static defensive organism.
Though this is tactics, so that doesn't really factor into if they're better than Zoanthropes, which, well, is as said above, purely situational based on what kind of army and armour you're facing.
