I always struggled with the corner shots because I have less of a spacial reference with the side of the backboard facing me. Shooting from the top of the key should be much easier, no? I always had the most success with the 45 degree angle one, right between the key and the corner. Maybe that’s just me though.
Not only is it nearly two feet closer, but once you get used to the distance, the lack of a backboard isn’t a huge deal. I find left corner threes to be the easiest after a few months of practice.
