World Championship in Heroes of Might and Magic III.

We need an urgent vote or a tournament – Castle vs. Swamp! :D
But seriously, I might have expressed myself incorrectly. I meant two things: in battles with a large number of native troops (let's say, the increase over a month), with equal heroes and without overpowered magic, Swamp wins quite easily. And secondly, in real matches, Swamp has more attacking stacks, and they are recruited faster.
