One of the best comparison is Paladin compared to General. Paladins have the same defense as Generals(though its harder to reach for most units) in addition to superior all around and higher movement. The only caps General has above Paladin is STR by 2 and Luck by 5, everything is either equal or much lower then Paladins.
A similar comparison is Horseman vs Swordmasters, where the only stat Swordmaster has an advantage is skill by 1 point. Every other Horseman Cap is equal or Superior to the SwordMasters.
I still love the DS games, but I wonder whats up with those stat caps? Perhaps Swordmaster and General were really just intended for quick utility rather then final classes.
