Despite the cost, I like Lightning Lane much better than FP+. The system absolutely needs to be tweaked though. Two upcharge attractions per park doesn't make a lot of sense when you back into what you can actually ride with Lightning Lane. If they dropped the $15 charge for Lightning Lane, removed the unnecessary attractions that they include to "add value" (shows, typical walk ons, etc) then it would be fine.
Part of the reason people liked MaxPass is that it didn't include unnecessary attractions. The other MaxPass decision that I prefer is that you can only use it once you've checked into the park.
