In all honesty, what I am finding is that the proponents for FP+ (there are a few of them) are REALLY digging at ways to defend the system. The faults, of which there are an abundance of them, are obvious to everybody. Yes, people have different ways of touring. We all agree upon that. However, it's a very simple, mathematical fact - Under the new system, we are getting less. I'll give you this quote from the Unofficial Guide on FP+ which really tells you all you need to know and is stated perfectly:
More bodies in beds at Disney resorts aside, Fastpass+ is a complicated system that rescinds certain privileges enjoyed by all Disney World guests since 1999. The end result, except for a few fortunate Disney resort guests, is that it will take more time to see less with Fastpass+. Humans respond negatively, sometimes angrily, when something of value is taken from them. We expect Disney to endure backlash on Fastpass+ eclipsing that which is received regarding its ever-escalating ticket, dining, and hotel prices. Compromising a guest's time and quality of experience is more personal than gouging on elective expenditures like food and lodging.
