The first reason Fall is the best season is it's physical changes it brings. The second it hits this season brands, nature, clothes, weather, and homes all under go their respective changes. For example brands like starbuckss, dunkin, and cinnabon all start introducing the pumpkin spice, cinnamon apple and brown sugar fall flavors we all know and love. The world starts to change colors, quickly cool off, and romantizize something a simple as a drive to the store. In the very last transition of Fall we see houses start to be become homes, firplaces, hot drinks, blankets scattered, and warmer thingds. 

The second reason fall is the best season is the change in people. People are so much happier when they have a little peaceful change around them so they change within. New flavors, new weather, new clothes, and new customs all create a new mood. I think people are happier when they are cozier and fall is the coziest season there is. People now look forward to the heat after dreading it for so long. The new season uplifts spirits. Not to mention it's the start of the best holidays to come which is another huge mood booster.
