In terms of durability - both are durable
looks - the innova has the edge since its a new design, adventure is an old design since 1998 and it just had numerous upgrades
interior & exterior, features, and operation - innova wins in all of this newer design, better driving ergonomics,
maintenance cost - Adventure may win because of the simplicity of its parts and old designed engines. This is in consideration that the engine is to be overhauled. But if its normal wear and tear both innova and adventure would just be the same in cost
