Supermarket brands versus other brands

I'm trying to save a bit as everything is so expensive now so when I've been supermarket shopping I've changed to their own brands. I'm delighted with Tesco washing bio liquid. Find it just as good as Persil which has always been my go to. Tea bags - love M&S gold tea bags but very happy with Sainsbury's or Tesco equivalent. Shout replaced by own brand - appears to be as good. Am still buying Burford brown eggs as we really like those. Own brand bleach.

Any tips for anything else you find just as good or if not better.
