Oh man. That's a good question. I guess to answer it best, I need to ask a question. What do you want to do or envision doing with a drone? Drones are tools, and like any tool there's a right one for a given job...
The old saying of "the best camera is the one that you have with you" applies here, and I think that's one of the reasons that a Mavic Mini is cool, because it's so small it can go anywhere. Yet the small size lends to several drawbacks, like limited wind performance and the small size means that you're not going to (legally) be able to fly as far away from yourself and your VOs than you would a larger drone.
That being said, I can pack a Mavic 2 Pro, batteries and all of the gack i need with me in a pelican box the size of normal person's shoe box, and when I'm working out of a backpack, I can do the same with a few packing cells so it's not that hard to pack around either. The M2P is more appealing to me as it has much better flight performance (wind tol) and takes higher rez photos and videos and I can see it further out.
The Mavic 2 Pro (M2P) also has six axis obstacle avoidance. I believe the MM just has it upward. Either way, DJI's experience is so Apple-esq. that you will be up and flying in no time.
