It always cracks me up to see the differences between the two. We'll be there next week, and for Monday (MLK), for instance, TP has MK as the best park, whereas Easy says that MK will be "by far, the worst Park to visit today." Long story short, we're going to MK that day.
I do look at both of them when deciding where to go. Josh's explanations always sound reasonable and make sense, but I don't really know what's backing them from a data standpoint. On the other hand, I know that the TP recommendations are based upon hard data that's been culled by many people over many years. With that in mind, when the two conflict in a serious way, I trust TP more just because I know that there's an absolute avalanche of data behind that projection. Maybe Josh uses a lot of data, too, but, it's not something he trumpets about, if so, so for the time being, TP is still the one I go with.
