Why Nintendo Wii has edge in console for Nintendo DS?

Wii has better games and also the nintendo ds. I have a nintendo ds and it has a lot of games but I don't own a nintendo wii.

But I cannot compare the two because it has both marios, But in terms of graphics wii is superior to ds, many says that wii games at targeted to casual areas but it has many fun rpg games, but the nintendo ds has a large rpg so maybe ds is better.

Both consoles are always updating their firmware to ensure better software support and bug fixes. Everyone has different taste and fanboyism is always common whether what is the superior product.
