This picture shows a boost from strength scaling (shown by the blue numbers):
Scaling boosts the damage that you do with any particular weapon, depending on which stat(s) and which level of scaling are defined (S, A, B, C, D, E) as pointed out S being the best, E being the worst. Scaling plays a big part when choosing the right weapon, in any situation. Medieval bowyers used yew almost exclusively for making the famous English war bows. However, as individual bowyers have their own preferences, some choose to make longbows from white oak, red oak, hickory, red elm, American elm, Osage orange or rock maple instead. To answer this question, it entirely depends on what stats you are focussing on. Yew is typically regarded as the best wood for making longbows.
