What's your budget and what's your intended usage?
Get a newer iPad. The Air 2 doesn't have hardware HEVC decoding.4k movies and tv shows.
Get the 6th generation iPad then.4k movies and tv shows.
Oh no, the difference is real, and you can clearly see and feel it when comparing with a10 or a9x. Having said that the air 2 is still very usable with ios 12. It's definitely better than ipad 5, as to 6th gen, it really depends on your priorities. If you don't care about the pencil it can be better, it's thinner, slightly lighter and less reflective, but as mentioned it has no hardware HEVC decoding....I think that the Air 2 is a better device than the 5th and 6th gen iPads. Lighter and thinner device as well as a better screen.
You only go down on processor, not even RAM. And from A8X to A10 is not a real difference.

Technically, that's A8X/2GB, A10X/4GB and A12X/4-6GB so you don't really have all the requisite devices to disagree.Owning the Air 2, 10.5 Pro, and 2018 12.9 Pro, I'd really disagree with this assessment.
