Okay, I can't imagine how this is true. Granted, I've not used PP+ so maybe I have it wrong. But what I THINK it is is having to choose a measly THREE fastpasses two months in advance, from TIERS where you cannot choose BOTH RR and TOT or BOTH Soarin' and TT and probably others I am not thinking of, too. And that AFTER you use your the third FP you can then select a fourth, but there are usually no good FPs to choose from because they were chosen and booked two months ago!!
Disneyland's legacy FP is so much nicer because you can get your FPs as you go along. With the addition of MaxPass you can book your FPs from your phone/app and not have to run around to the ride kiosks first anymore. So if you're willing to pay $10 per person per day for MaxPass you are getting the convenience of booking FP from your phone all day long and the passes you want are there because they weren't snagged two months ago. If you chose not to pay for MaxPass then you still get the awesome legacy pass where yes, you have to run around to the ride kiosks to obtain the FPs, BUT you can have as many as you want allll day long and again they are available because they weren't snapped up two months ago!!
Unless I am seriously misunderstanding FP+ I don't see how on earth it could be better than legacy FP with zero tiers and zero limits. Also with MaxPass you can get your next FP only ninety minutes after you got your last one, not two hours (of course if your ride return time is earlier than that you can get your next FP as soon as your window opens up).
