What were the advantages and disadvantages of the French and British troops at the beginning of the war?

Army of England: the advantage was a strong fleet, they seized the initiative at sea at the very beginning of the war, as well as a relatively inexpensive army of cavalry and infantry, the main last were the Welsh archers. They fired far and accurately. Good artillery was also a plus; from 1346 they began to use it in the field. The downside was the small amount of cavalry, but this was rarely felt.
Army of France: the advantage was the number, a lot of heavy cavalry and mercenaries, for example, crossbowmen from Genoa. There were many disadvantages at the early stage of the war, that is, in the XIV century, and therefore they fought so-so. The main one was a poorly organized knightly army, the crossbowmen were inferior to the English archers.
