I think you have to compare two of each phone. That's how I noticed that my Huawei had slightly more storage space, and better battery capacity and life span, in contrary to a Samsung device of the same price, which could only make slightly better pictures and recorded clips, and more expandable memory. Both are good, but I don't take enough pictures and make clips to fill that much memory and to make good use of the camera, whereas I'd like to use my phone as long as possible when I'm not home and go with it for as many years before needing to buy a new one.
I always go cheap though, my money goes into computers
