M.G. Siegler on being asked which iPad is the one to buy:

When pressed, my answer was that for most people, the 9.7″ iPad was probably the one to get. With the latest iterations of the iPad Pro, I think the answer is now much more clear: the new 10.5″ variety is the one to get.

The screen size gap has been closed a bit. The speed gap has been completely erased. The 10.5″ iPad Pro is absolutely amazing.

And:

When you start to use the 10.5″ and then try to go back, you cannot. The 9.7″ iPad feels short and stubby in a way similar to how the 3.5″ iPhone felt after using the 4″ variety. The smaller one now feels like a clown iPad.

And:

Size aside, the screen with its much touted 120Hz refresh rate is incredible. Again, it’s one of those things you have to either be a hardcore iPad user or use a newer iPad Pro versus an older iPad side-by-side to truly appreciate. Everything is just so much smoother.

At first, it’s a little weird. It almost makes some iOS animations like swiping through your app screens feel like how pan-and-scan used to feel on old non-lettered-boxed VHS movies. But this feeling goes away quickly and now it just seems normal. And old, non-120Hz animations now just feel janky.

The recommendation for the 10.5″ iPad Pro seems almost universal. There may be a review that didn’t love it and appreciate the leap forward in terms of product capability, but I have not run across it.
