Have you had a look at the Affinity suite? It certainly can't replace everything, but for many users like me it's not really missing anything for a one time payment.
They have -30% sales sometimes. I actually bought the whole suite at 50% discount some years back, but I don't think they've had another 50% discount for a long time now.
If you're interested in any of the Affinity programs, keep an eye out for sales. I'm guessing the next one will be Black Friday / Cyber Monday.
If you’re some dude who edits photos for his kids or makes bday cards for their family, there’s literally a dozen or more free image editors that work just fine.
If you’re in the industry, then you’ll quickly see no client will accept or work with an affinity file. Or a gimp file. Or a photomater file.
Adobe is the de facto standard and their monopoly is only getting worse. It also doesn’t help that schools are basically shills for Adobe. So every kid comes out knowing Illustrator and Photoshop and nothing else.
