The OC family use case
Club soccer at Great Park, school runs to Santa Margarita Catholic, three car seats across, a Costco trip after practice, and one 300-mile weekend to San Diego every month. That's the OC minivan brief. The Odyssey and Sienna both do it - very differently.

The MPG conversation
The Sienna's biggest single win is that it's a hybrid - full stop. 36 mpg combined vs the Odyssey's 22 is not a small gap; over 15,000 OC miles a year it's roughly a $1,200-$1,600 fuel savings. If you commute long or road-trip often, the Sienna's math is hard to argue with.
Where the Odyssey wins
The Odyssey drives noticeably more like a car. Steering is sharper, ride is more composed on Antonio Parkway, and the 3.5 V6 has a real reserve of power for merging onto the 5 fully loaded. Cargo is dramatically better - the Odyssey's second row physically removes, which the Sienna's does not, so the max cargo number isn't close.

Which one for South OC?
The Sienna wins on pure efficiency and AWD availability. The Odyssey wins on driving feel, cargo flexibility, and family versatility.
