I think that pretty much only two nations will give Hinnom a strong challenge, or may I say, beat it on equal skill level, in early game.

One is Sauromatia. Poison archer is the bane of many things, esp. small elite army of Hinnom. E blessed amazon riders can easily raid Hinnom PDs. 25 PDs cannot stop 10 E9N4 blessed riders. Hinnom can expect to counter poison archers with baals, but in turn, hydras scare the pants off those poor baals.

The other is Niefelheim. E9N8/9 blessed nief giants and jarls, with its cold spreading domain, can easily beat baals and Hinnom giants 1:1, with any bless.

From middle game on, it really depends on the skill level of player and too many other factors to predict.
