FWIW in the 2004 (I think) and onward Pilots, the second row scoots forward, so that the third row can have more leg room. Jessi and I had a really confused conversation last week, until I figured out that the 2003 second row doesn't move up, lol. You can put a RF seat in the second row, or in the third row, but not both for the most part. (I do have a CCO behind an upright Scenera behind the passenger seat, which is scooted up a bit, but for the most part I would say it's an either/or.)
I also wouldn't say the Pilot has more room than the Odyssey, although the eight seats as a whole are more functional than the 7 plus the Plus One. But cargo room is minimal with all three rows in use.
On the up side, the third row is such that my kiddos pass the 5-step back there when they don't in any other seats. That might help with width issues, depending on the ages of your kids. I usually avg about 18mpg but on a recent series of days of highway/country road-only driving, I got almost 24-25!!
