It's great, and what makes it so great is exactly that. It's highly possible to brew 5 gallons batches with the very same ingredient quality as any microbrewery and a process which is the same but at a smaller scale.

You also have to advantage over microbreweries to be more creative and test out stuff in your recipes because making 5 gallons of not so perfect beer is not the end of the world. All the professional brewers I know were homebrewers before and still are.
