You're comparing a very basic microquad that will easily fit in the palm of your hand with a quad with a 550mm frame, 20 minute flight time, and autonomous flight capability.
The 20 minute flight time is nothing to brag about... the much cheaper microquad apparently flies for 10 minutes. If you want a drone with real flight time, you need to go with a plane-type craft.
The micros realistically get 5-7 minutes.
That's like comparing a Tesla to a Hot-Wheels car.
Probably more like a Tesla VS gas powered go-kart.
