I have the exactly the same iPad. I got it at launch and had it swapped out after a couple of years when the home button started to fail. So, I have been using that model for six years. It has been one of the most useful items that I have ever owned. I now also have other Apple products.
I was eagerly watching the latest launch and waiting to buy. However, when I went into the store to see it for myself, I was underwhelmed. I explained to my wife that there were smaller bezels and face ID and as I was doing that, I was also thinking, gee whiz. I felt stupid talking up, basically, nothing of real benefit to me.
Yes, it is faster and has new features, but for me and most other people, even after six years, there isn't a compelling argument to replace a perfectly good iPad with a new 'Pro' mode.
