The short answer is that users will say that their needs are met by the GIMP along with any number of free or nearly free tools. The larger question might be "how high does one need to jump" to do a required task as well what tasks they use it for.
I use Affinity Photo for my raster editing. It is an amazing tool with editing that is sufficiently similar to Photoshop to make it very attractive. I don't use it for digital RAW processing or for content management. I also don't use it for its gee-whiz features.
I use Adobe Lightroom for the bulk of my photo work flow, including film scans. The selling points for me are the content management, RAW processing, virtual copy features, edit-in, soft-proofing, edit-in, printing, and publish (export) to target features. I will add that I have a legacy desktop version of Lightroom 6.x and am not paying subscription.
On the side are HDRMerge for HDR and Microsoft ICE (sadly, no longer available) for panos and other composites. I also maintain an up-to-date copy of Pentax DCU for the odd task.
