I have been testing the three big Book layout and design software tools for the past year or so. After building books in Scribus, Adobe Indesign, and Affinity Publisher, I have settled on the group of design software tools I will be using going forward. I am standardizing on Affinity Publisher (and related Affinity programs).
The Affinity group of programs, Affinity Designer, Affinity Photo, and Affinity Publisher together cover all the major tools professional designers traditionally go to Adobe Creative Cloud for. If Affinity was buggy or limited in scope or unsupported, you might say that you get what you pay for, but from my experience and the experience of others who are moving to Affinity from Adobe, the Affinity programs are stable and provide all the needed tools.
In short the hunt is over – Affinity provide the professional design tools tools I need and the fixed price lets me keep the cost of designing books as low as possible.
