In my personal opinion Winsor and Newton acrylic paint is much better than Daler Rowney. Both Winsor & Newton and Daler Rowney are well-respected brands in the art materials industry, and both offer high-quality products. However, to me, Winsor & Newton acrylics have better consistency, are more opaque and performant than Daler Rownet paints and are more durable. I love Winsor&Newton heavy body acrylics, using them for impasto techniques and mixed media art. Ultimately, of course the choice between Winsor & Newton and Daler Rowney may come down to personal preference and the specific needs of the artist.
