In my opinion the best alternative to the Adobe suite (Photoshop, Illustrator and InDesign) are the Affinity suite - I use all on a daily basis as a professional graphic designer and have done for some time now.
No subscriptions to worry about and the software is super polished and fast.
Now is a great time to get the three (or whichever you need) as they have 50% off.
Affinity Designer: Illustrator equivalent
Affinity Photo: Photoshop equivalent
Affinity Publisher: InDesign equivalent.

I agree with OP. Great deal on great software. The online video tutorials are also first rate if you are just getting into photo editing/design or just need a refresh.
