I typically refrain from engaging in the Fast Pass discussions as they are very polarized. In this case, however, I will entertain the discussion and hope that I can add some salient points.
My wife and I enjoy FastPass+ with what it offers. I am not going to dispute the differences between a KTTW card vs. the band. That boils down to semantics, fashion, etc., but in the end is just the vehicle for the technology that WDW is now employing at their parks.
There is the argument that WDW now offers more than less with FastPass+. I find this argument fascinating as it is solely based upon the fact that the determining factor in anyone person's enjoyment and/or value of a particular park is by the number of rides one person can physically ride in a given day. If that is the barometer by which a park is measured then the individuals that fall into that category will be disappointed. To those individuals, FP runners are a necessity as the mode of attack is the "park commando" and it is get the most bang for your buck by physically going on as many rides as possible. I visited the parks several times and attempted this level of "enjoyment" and found it to be a dissatisfying experience. As the father I was termed the runner and found this job extremely uncomfortable tearing across the MK for the next FP as the family stood in line. Comparing this to the current situation, I find the FastPass+ option to be offering more instead of less in terms of the overall experience of touring the parks.
Additionally, we do not rise with the sun in my family so we were never into park openings, a key component of the commando strategy. Another part of FastPass+ that is to me an improvement over the old is that I am entering the park with 3 FP+ already in hand, not needing to run at rope drop to obtain my first coveted paper FP - which, by the way, you can't easily change once you get one. We have already changed FPs in line multiple times when we decided to change our plans on the fly. This to me is also an improvement over the legacy FP system.
What is important for my opinion here is that I am not of the park commando breed. My enjoyment of the parks is at a more leisurely pace, as I like to enjoy the theming, landscaping, people watching, etc. For me, this is a better experience so yes, I find that FastPass+ offers my family more. To simply state that legacy FP allowed for the potential for more rides makes the new FP+ less valuable is a weak argument as there is so much more to a WDW vacation than simply the number of rides one may go on.
Also, I was under the impression that you are no longer limited to three FPs per day. Furthermore, the added FPs can be used in the other parks. This new system is and will continue to be "improved" upon (I added quotes as to me they have been improvements, to others not so much).
