With a larger wheel, you have more contact with the ground, so you have better traction whether you're braking or cornering or any of that stuff. Also, with bigger wheels, once you get them up to speed, they roll faster.
If it's a question about stuff that matters to you personally, like favorite food, favorite piece of knowledge, favorite animal, it's hard not to have an opinion and want to quantify things.
In sooth I know not why I am so sad. It wearies me, you say it wearies you; But how I caught it, found it, or came by it, What stuff 'tis made of, whereof it is born, I am to learn.
