From my understanding (based on discussions with other tech heads - and regular discussions on a guy who reviews these products on a frequent basis) is that the Huawei phones are almost a 1 trick pony.
They offer zoom better than anyone else, and low light photo they excel at, but when it comes to video (and esp video in low light) they fall a fair bit below their competition.
I would have though the Samsung offering would be better in this case, (unless zoom is your thing)?
I have the OnePlus 7T, which is actually extremely impressive - you can find many many reviews on Youtube of reviewers comparing this to much more expensive phones - because it genuinely can compete at that level. It usually doesn't come out as a clean number 1, but really does most of the things so well that you can't really complain. When you factor in how much cheaper it is, for me it's a no brainer.
Still, if you want the ultimate, then the Huawei is the wrong way to go, the iPhones this year are pretty much the king when it comes to all things photo/video related - they truly have excelled way past any competition this time round. As much as I hate Apple/iPhones, I cannot say anything negative about their cameras - mighty impressive indeed!!
