Personal bias toward/against FP+ is definitely a factor, and I guess there's enough snark on both sides to feed into it!
Are you going during Christmas? We usually go during slow times but next year I'm planning on the week before the week of Christmas, which I know is busier than I'm used to. We have the DVC discount APs so the ticket price is less of a factor. I figure that it will be a much different trip as far as expectations go.
I haven't gone during Christmas week since I was a kid and I've never gone during the summer or Spring Break. Since I don't have that perspective, how easy was it to use fastpasses before as opposed to now? I was under the impression that all the rides (not just the headliners) had crazy lines - I've seen the extended queue pictures on EasyWDW!

So with legacy FP did you get to ride more rides, or get more duplicate rides on popular rides? When the FP- return times became enforced didn't it cut down on some FP- use? I'm honestly curious since I have no real experience with super-packed parks.
