Which third-level creature is the best?

But will dragonflies really crush the ice elementals completely? There's a definite difference in health...

So, I conducted a "test drive": D between these creatures. Everything is as it should be, with parameters, morale at zero, and so on..., in general, equal conditions. They fought in groups of 1111, i.e., 1000 vs. 1000, 100 vs. 100, 10 vs. 10, and 1 vs. 1
Starting from the left, the number of dragonflies that survived:
332
33
5
1

Conclusion - a complete victory over the ice elementals, despite the difference in age, well..., in health, damage, and parameters. The priority of the turn did its job, and the weakness also helped nicely.
