Which level 1 monster do you like the most in Heroes of Might and Magic V?

In version 2.1, retraining is limited by the number of units per week, about 20 units maximum, so peasants are not very useful.

They also promise to limit it in 1.5. Then it will be more profitable to train higher-level units. But for starters, 20 additional archers are also good. Then there will be money left for archangels.
