We just bought an '09 Ody and I had narrowed it down to the same two vehicles.
We have three kids, ages 8, 5, and 7 months. So, booster, ff'ing harness for a few more weeks or months, and rear facing convertible seat. The van works better for us b/c our 8 year old can get in and out of the back (third row) much easier than in the Pilot. I really wanted the Pilot, but the Ody works much better for us. In the Ody, you could fit one booster kid on one outboard seat, one booster kid in the center "plus one" seat *if* it's a really narrow booster, and the rear facing nephew on the other outboard seat. As long as both boosters are easy to move out of the way (small, lightweight, non latch), you'll have easy access to the third row, but it's not a great center seat for anyone. OR you can use the plus one seat as a drink holder (it folds down for that) or remove it, put rear facing nephew on one outboard seat, and let one or both of the booster riders ride in the third row. OR you can remove the plus one seat, and slide the outboard passenger seat towards the center, making an easy aisle to the third row (much easier for bigger kids or grown ups to access the third row!). You may be able to *ALL* ride in the Ody this way. Both teens in the third row on either side of a booster rider OR one teen in between both booster riders. You've got options. The van will pull a trailer or a pop up or a small boat.
Every van we've had has pulled those things with no trouble. And lots of storage behind the third row, even with it in use.
The Pilot, OTOH, won't allow you to swap the seat configurations around, BUT three in a row in the second or third row is probably easier to fit, but harder to access. Teens would probably think it's way cooler to ride in the Pilot. LOL A bit less storage or carrying space in the back. Nice to drive. Pretty comfortable. I really, really liked the size of the Pilot. I still sort of wish for the Pilot. LOL BUT then I think of the nice sliding doors on the van and the ease of getting the little kids in and out...and I'm over it! LOL
In your shoes, esp if the booster riders are older ones that won't be in boosters for too much longer, I'd pick whatever makes you happiest. They both have side curtain airbags and other nice safety features. And older kids won't have as much trouble getting in and out or need as much help, so that's less of a consideration.
GL!
