The short answer
Both are excellent minivans, but the Toyota Sienna is the better long-term value. It wins on fuel economy — 40 mpg combined, hybrid-only — and resale, losing just 36.4% over five years, while the Honda Odyssey wins on cargo space and driving feel. Annual repair costs are nearly tied: about $554 versus $547.
Is the Toyota Sienna or Honda Odyssey more reliable?

Both are built to clear 200,000 miles with maintenance, and Toyota and Honda routinely top reliability rankings. For the wider picture on which badges go the distance, see our guide to the most reliable car brands.
Which minivan has better fuel economy?
The Sienna wins decisively. It's hybrid-only and rated around 40 mpg combined, while the V6 Odyssey is rated about 22 mpg city and 28 highway. Over 12,000 miles a year that fuel-cost gap runs roughly $800 to $1,200, depending on gas prices and how you drive — a real factor for a high-mileage family van.
Which minivan holds its value better?
The Toyota Sienna. It loses about 36.4% of its value over five years versus 43.4% for the Honda Odyssey, per iSeeCars — a 7-point gap worth a few thousand dollars at trade-in. Strong hybrid demand and Toyota's resale reputation keep the Sienna's residuals ahead across most trims.

Which minivan has more cargo and passenger space?
The Odyssey edges it for maximum cargo, offering about 144 cubic feet behind the front seats versus roughly 101 for the Sienna. Honda's Magic Slide second-row seats add unusual flexibility for car seats and walk-through access. Both seat up to eight and swallow strollers, luggage, and sports gear with room to spare.
Should you buy the Sienna or the Odyssey?
Choose the Sienna for the lowest fuel bills, the best resale, and available all-wheel drive — the smarter long-haul value. Choose the Odyssey for the most cargo room, the most flexible seating, and a more engaging drive. Repair costs are a wash, so the decision comes down to efficiency and resale versus space and seating.
- Pick the Sienna if: you want hybrid fuel economy, top resale, or all-wheel drive.
- Pick the Odyssey if: you want maximum cargo, flexible seating, and a sportier feel.
