The variants in Dragon are a bit more different from the standard paladin than the UA ones are (although those have their own quirks) - the Corrupter's Smite Heathen targets divine spellcasters of other faiths and can use Turn Undead-like mechanics to turn off divine spellcasting, for instance, the Despot gets Leadership instead of a mount and can sicken/nauseate at-will through Turn Undead-like mechanics, rather than a special mount the Incarnate can summon elementals...

Most of them aren't that good, of course, since they've got a tiny spell list and none of the ACFs that Paladins of Honor have.
