I use my Ipad for streaming live sporting events. Since it is on the tripod mostly, I want the largest screen size to see things as possible, so I love the 13 inch. Plus with m 2 TB drive, never have to worry about running our of space for the 4K video. Now, I use a 10 inch Ipad as my score controller which sits on my lap. So, I just have all the tools needed to have the best one fit for the job.
