Welcome back Joe,
The Mavic 2 Pro is a great drone, I have not used a Dji SC but have heard good things, about the screen resolution, and the brightness.
Obviously any purchase you make now will mean the MP2 will become a legacy drone on 31/12/22, and under the new drone classification, personally I would hold tight, you already have a great drone or opt for a MM2, unless you are prepared to undertake A2 Cofc course, until the consumer classified drones start hitting the shelves,
Thank You, I have heard of the new regs coming - need to look into to see what is coming.
