No scientific proof at all but it feels like washing powder does a much better job at removing stains than washing liquid.
It also seems more and more difficult to find washing powder in store as manufacturers are moving to liquid and even more a rip off - pods. Don’t get me started on these money spinners.
What is your experience and what works best?

I posted the recipe here, I did the research myself based on ingredient lists, break downs of ingredient functions, and trial and error to decide ratios.
