It's like with anything else, some people prefer one brand over another, Coke over Pepsi etc. A 1050 Ti from anyone is going to perform much the same as any other 1050 Ti.
So then, weed out the ones that aren't in your budget. Then weed out the ones that lack the elements you're looking for. Maybe consider which brands seem to have the best reputation. I tend to buy Asus, EVGA, and MSI because I've had good experiences with them.
