I've switched from AI to Affinity Designer, and I'm overall very happy with it. The one fly in the ointment, however, is that there's no way to automatically save a whole image as a tiled, multi-page PDF. Slices are great, but they seem more useful when you just want to excerpt a small portion of a file - having to draw out page-sized slice after page-sized slice is laborious and fussy and leaves room for error, and then there's the issue of bleed ...
I have a small business selling sewing patterns for historical costume, so this is something I do a lot. (All my patterns are digital and print-at-home.) It would make things enormously easier if I could just go Export -> PDF -> letter/A4.
Thank you for considering this!
