A good professional alternative is Affinity. As a graphic designer, I have been using their products for 4 years. They have representatives for three key areas of graphics:
Photos and raster graphics:
Adobe Photoshop ➡️ Affinity Photo
Vector graphics:
Adobe Illustrator ➡️ Affinity Designer
Print materials, typesetting:
Adobe InDesign ➡️ Affinity Publisher
You can purchase their products for a one-time price (as opposed to a subscription like Adobe) and they currently have a 50% discount.
