I had a Samsung Galaxy S3 mini as my first smartphone, and when I was looking for a new one, I had my eyes on the same brand, but then my girlfriend recommended me to compare one Samsung device (which name I forgot) to the Huawei I currently have. Both had the same price in 3 different stores (avg. €250,00), and were pretty much the same on all points.
There were two things different, one thing was better on the Samsung, I think quality of pictures, and the other was better on the Huawei, which I think was the RAM or Memory space. I choose the Huawei P10 Mini, because that slight difference was better for me, but someone else, who would make more photo's, might chosen for the Samsung, because it could snap better pictures.
What I'm getting at is, pick what suits your needs. Both have Android operating systems, and the apps already installed aren't really that different in quality or quantity, at least not that I know.
If you really can't decide, stick with what you know is good. Why pick plan B if plan A works perfectly fine?
