I see this question is nearly a year old now, forgive me for reviving this, but in case you're still looking, (or for others who wander here on the same quest).
I suggest checking out Affinity Photo.
For vector work, Affinity Designer is also pretty good and acts as a direct competitor to Adobe InDesign. It's amazing how easy it is to work on the same file in both suites, it feels seamless, like you're just changing the workspace.
