I love the new system as compared to paper FP and pre-FP.
Pre-FP - get to park at opening, enjoy 5-6 attractions before lunch, then wait in standby lines for the rest of the day, getting about 4-5 more attractions before dinner, and maybe 2 more after dinner. 11-13 total attractions, 3-4 hours in lines.
Paper-FP - get to park at opening, split up and run around park to get FP for popular attractions while rest of family enjoys an attraction, then do an attraction, repeat process for rest of the day. I got a lot of steps in, but generally we enjoyed 5-6 attractions with FP, 4-5 attractions without FP, and those who didn't run around to get FP did 2 more attractions. 9-13 total attractions, maybe 2 hours in lines, very exhausted FP runner.
FP+ - book 3 attractions at times I choose in advance. Get to park at opening and enjoy 5-6 attractions before lunch (1 with FP+), then do 2 FP+ and 3-4 attractions that get lesser lines (shows, usually), maybe 2 more attractions after dinner. 12-14 total attractions, maybe 2 hours in lines.
Yes, it takes some planning to do the newest system, but in our situation it definitely seems to work the best. We plan them out so we don't have to run around the park. If you book them at the window opening you usually can get some choices of times and attractions; if there are headliners you MUST do and can't get FP+, then do them at rope drop (which is likely what you were doing in the old system anyway).
