That's a completely different class of robot. The Beni robot is just a toy, it's just connect the app and drive it around, record videos and do some fancy tricks like flips. It is not meant to be a platform you program yourself.

The Microduck is meant to be a hacker toy. Train it yourself, write software, hack it, etc.

It depends what you're trying to get for your daughter. Is it something to get her into robotics? Then probably the Microduck is the way. If it's literally just a toy, then the Beni robot is better because that's literally all it is.
