The DJI Phantom 4 Advanced and SwellPro Spry drones are both excellent choices for those in the market for a high-quality drone. However, there are some key differences between the two models that should be considered before making a purchase. The Phantom 4 Advanced is a more expensive model, but it offers features that the SwellPro Spry does not, such as a longer flight time, a higher maximum speed, and a better camera. The SwellPro Spry is a more budget-friendly option and is a great choice for those who are looking for a drone with similar features to the Phantom 4 Advanced but at a lower price point.
