Which faction do you like the most?

Yes, it’s not easy to play with demons at the start; there are no archers, and they won’t appear soon. Imps and demons are not very effective in fighting archers, except, of course, for the higher-level ones; they can jump in almost immediately if they’re lucky. Because there are no archers at all, the start is difficult, even for the Elves, who have archers of level 3, while demons only have level 4 archers, and you won’t be able to make them until the second or even third week.

These guys have the most unstable gameplay.

I agree with that; they lack stability. By the way, I started playing with demons in Heroes 5; it was a good experience, and I learned a lot about their abilities and the race in the campaign for Agrael. The race isn’t bad; you just need to know how to play it.
