I haven't got a chance to test drive pilot yet but I don't think I would be able to compare spaces visually that are visually close. From what I found

Telluride
Cargo Volume (SAE): behind 1st row / behind 2nd row / behind 3rd row
87/46/21 cu. ft.

Pilot Sport
Cargo Volume (behind 1st-row) 87.0 cu ft2023 Honda Pilot – SUV | Honda / 111.8 cu ft2023 Honda Pilot – SUV | Honda2023 Honda Pilot – SUV | Honda

Cargo Volume (behind 3rd-row) 18.6 cu ft* / 21.8 cu ft*

Pilot Touring

Seems like SAE J1100 standard plus measures volume under the lid of storage well which just SAE doesn't. Based on the number didn't change between sport and touring trim for former but did for later. So I think Pilot might have advantage if you want to use that space.
From numbers it seems like combined leg space is 1 inch lesser in Pilot than Telluride. I think Pilot is making up for space difference in interior height.

Embargo is lifting tomorrow, watching review from journalist might be helpful or taking measuring tape to dealership.

The SAE J1100 definition does not explain for the massive difference between the cargo volumes behind the 2nd and 1st rows, in the case of behind the 1st row, about 25 cu ft, they must be counting all the nooks and cranny in the car including cup holders and under the seats!

At the end of the day, the Pilot realistically increased about 2.0 Cu Ft in cargo volume behind the 3rd row seat (to 18.6 cu ft), the numbers are the same for the 1st row and second row as in the 2022 model., it still lags the segment leaders Telluride/Atlas/Traverse.

Definitely pilot has grown. Combined leg space increased by 3.1 inches. Second row did get most of the increment (2.4 inches). I am pretty sure it is still behind telluride but I don't think by much once you consider the extra volume in hidden storage well under the lid, otherwise it would suffer (especially if you store middle seat).

The Telluride has lots of storage place in the storage well, I am not certain that the Pilot has more; in fact I'd argue that the Telluride may have more usable space because in the Pilot Touring, for example,, it is compartmentalized into 3 portons. We'll see what the reviewers say once the embargo lifts tomorrow.

Here, Redline Reviews says the cargo space behind the 3rd row is about 18.8 cu ft, so technically, about 2 cu ft more than Gen 3.
