I do get what you're saying, but you're not quite understanding what we are saying. You can't just compare units one on one and expect that to give you any meaningful insights into the game. The only really way of judging a unit's effectiveness is on the battlefield in co-ordination with the rest of the faction's army. As you say, this is less clear, but tbh it doesn't matter which unit is better than another, all that actually matters is the result of a game.
