Dreft or..?

I'm a new mom of 2 weeks! Before my baby girl arrived I had my friend wash my baby clothes for us and she used her own bottle of dreft . Clothes smell amazinggg, baby reacts well to her clothes. I go to Walmart and literally stand there staring at these two detergents sitting next to each other.. like come on, one is 16$ with less amount of loads and one is almost 4$ with more loads. I feel so terrible ! I bought the Purex 😩 but in my head, we use purex on our clothes so the baby version should be good? Right? Even though growing up and recently I've only ever seen friends/family use dreft..
