comparison to the 5T seems a bit lacking
I've not used either phone so I don't know what the camera quality difference really is, but there are plenty of other obvious differences between this and the 5T that you'd think should be involved in a comparison.
Most obviously, the 5T gets a 6" screen into a slightly larger body, at 80% screen-to-body ratio; the Honor's 5.15" screen is only at 70% screen-to-body ratio. i.e., it's got giant bezels. Possibly more significantly, though, there's this:
Honor 9: LTE band 1(2100), 3(1800), 5(850), 7(2600), 8(900), 20(800), 38(2600), 40(2300), 41(2500)
5T: LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 17(700), 18(800), 19(800), 20(800), 25(1900), 26(850), 28(700), 29(700), 30(2300), 34(2000), 38(2600), 39(1900), 40(2300), 41(2500), 66(1700/2100)
that's....really lots more LTE band coverage. If you travel a lot, having a phone which covers a lot of LTE bands is super useful. It also makes it easier to switch providers. To me this is one of the bigger features of the 5T, and it's odd it doesn't seem to get much attention.
