Discussion of level 1 monsters.

Well, I don't think anyone chooses a faction based on its level 1 creatures. ;) So, it's usually not important which one is the "most powerful." But if you're planning to play with them, then Archers win this contest because they have the best survivability. I think if you gather about 1,500-2,000 Hobbits, they look pretty good (especially against level 4 units), and a large number of Wolves are also scary, but it's very rare to achieve that (although Wolves are easier to get). And if you just calculate the stats (1*1), I think Centaurs probably win. IMHO.
