[Embarrassingly basic question about Affinity versions and best uses.]

I have all three Affinity products. 

I need to make product packaging designs that will be printed on heavy cardstock with a blister glued on. 

Most of the designing will be pre-edited photos dragged and dropped onto the project of whichever software is being used.

The biggest task will be creating lots of shapes with color fill, rounded corners, borders, etc... over top of these photos. 

 

Which Affinity product would you recommend as the most user friendly for this task, from step one to sending to the printer without too many brick walls and wtf moments? 

 

Thank you all, I know this is the dumbest question ever...
