It comes down to your use, and how you’ll use it most. I’m fortunate to have 3 iPads which cover all my uses -12.9, 10.5, Mini. If I could only have two it would be the 12.9 which is perfect for nearly everything at home, and the Mini which is great for mobility. If I could only have one it would be the 11inch … I really wouldn’t put a 12.9 in my shoulder bag and take it everywhere, which I do with the mini and sometimes the 10.5. But I would really miss the 12.9, perfect for work and play, watching things, writing, doing art, making music, for me it is the perfect size, apart from portability.
