We have seen time and time again that old age isn't really a factor when it comes to the captain-commander. He dutifully plays the role of old man but is in fact more powerful then lets on. Beyond that there is a difference between being intellectual and being wise. Genryusai means sage. In turn Yamamoto is the basic eastern concept of the philosopher known for his wisdom and judgement. In other words the old mentor type. Think Yoda, Gandolf, Dumbledore type. They are powerful and wise from experience, time, ethics and morals. Aizen and Urahara excel at scientific or mental pursuits brought on through instruction. Thats the age old question which is better wisdom or intellect. Wisdom via experience and Intellect via instruction. Is he a scientific mind no, that doesn't make him less intelligent just not in the same way. Even Aizen's knowledge is more in manipulation than in science, while Urahara's is more in science and invention. Gin and Hitsugaya seem to be more knowledgeable in combat. So the question is in reference to what even genius's aren't good in every aspect some excel in one area rather then another. Trying to place everyone in the same category for no reason doesn't make sense.
