Before I even knew to hate Adobe, they were my favorite company to pirate from in college. Them and ChaosGroup
I am admittedly not a super-user, I basically only use vector and raster editing maybe once every 6 months, but for what it's worth I've managed to survive using affinity for most of my needs. I work in the AEC industry so we have a different PDF editor (thankfully)
I think affinity avoids getting under Adobe's skin by omitting certain popular features (for example, Designer still does not have image trace, which was probably 50% of what i used illustrator for), but otherwise they're serviceable
