Supposedly the PP is a Mid-Size 1-Row SUV, which is sort of a tweener stuck between Compact SUVs and Mid-Size 2-Row SUVs. There are other 1-Row Mid-Size SUVs, like 4Runner, Cherokee, Edge, Blazer, Outback, and Murano, but they all have different features and strengths so it mucks up any chance of 1-on-1 comparisons...
It's easy to compare 2-row Mid-Size SUVs like the Pilot, Highlander and a Ascent.
If KBB had compared those 5 Mid-Size 1-Row SUV's, I'm reasonably sure the PP would have also been #1...
Also: it's kind like the comparisons of the Ridgeline to other Mid-Size Trucks (Tacoma, Ranger, Gladiator, Frontier, Colorado), in the Street-only comparisons, the Ridgeline kills it, they love the features, and the super smooth ride, but the more "off-road" the comparisons go, the farther back the Ridgeline falls...
cheers...
