Which version of Heroes do you like the most?

Heroes 3 and Heroes 4 are both good, each in its own way, and I enjoy playing both. Heroes 4 is more beautiful, but also more complex, and there are more unknown techniques to me. Essentially, they are two different games. I think I'll reach 500 [points/level/something similar], and then switch to Heroes 4 to gain more experience, as I mostly play Heroes 3 right now. But neither In the Wake of Gods nor Heroes 5 appealed to me. It's a pity, the game takes up a lot of time, but there isn't enough time for everything.
