Coming from an iPad mini 4, after trying out the 10.5 Pro recently, I decided the iPad mini 5 was the way to go. Simply put, I missed the portability of the 4 and when I used the 10.5, the device itself was awesome but the form factor was just huge, simply too much for me. Holding it in bed just seemed a monstrosity lol. While I loved the screen real estate to use, the size simply wasn't something I was willing to sacrifice for it so I returned the 10.5 and went with a mini 5 and so far I have been ridiculously impressed with it.
I don't mind not having Pro-Motion on this, you simply don't notice it given the 7.9 display. Everyone is different on this, but for me personally the lack of Pro-Motion here is not a deal breaker. The lack of four speakers is not a deal breaker either, and in terms of the design yes it is a 7 year old design, but for me it doesn't bother me simply because I love the larger bezels which makes it easier to hold when using it. I don't know if Apple will ever update the design of this any time soon ( I thought the mini was dead personally), but for now, I don't see the fuss of having larger bezels and people thinking it's an eyesore. I simply choose not to let it bother me.
Not having a better camera is fine ( I take pics with my iPhone X anyway) BUT I do like having the improved 7 MP camera on the front for my FaceTime calls so I will take that. The look of the new Space Grey on here is truly slick too, it matches the Smart Cover I had for the mini 4 perfectly so I'm glad Apple went with the darker shade here. My gosh, that lightweight feel in my hands, it's glorious. I didn't care for the 10.5 size at all despite having all that power, the portability was just too much to overcome. With the mini, it goes anywhere I need it without any issue. What's really awesome is the display's P3 and True Tone additions which are most welcome, its a joy to look at. And that A12 isn't kidding around, I've done everything so far and it just flies, not a hint of lag. Multitasking, videos, browsing, you name it and it doesn't miss a beat. It really does show itself off next to a mini 4 which was no slouch to begin with!
In short, I'm in love with the mini 5 and would highly recommend it.
