I have pretty much the exact opposite position from Dr P.

Unless you have lots of money to burn, Red Guards are the only cavalry to recruit. Their stats are enormously superior to the regulars, and because they're sacred, they actually cost less in upkeep.

The Imperial troops are not that great. Map-move 1, questionable perks (high morale on archers?) and a hefty gold cost limit their usefulness.
