I tried Affinity Designer with Windows 10 and was pleased. I used to design a dozen posters a year for special events at our ice skating club using open source Scribus. To test Designer, I recreated one of the old (2012) posters using two pieces of raster art from the original. The "We LOVE Ice Dance" and the lusty skaters are copied from the old. The rest is done in designer using fonts from my computer (Biondi, Victorian NET, and Ariel Bold). BTW, the Affinity Designer WORKBOOK is a great help.
