I use Photoshop CC and Lightroom CC at considerable cost. I may soon go back to Photoshop 5 and Lightroom 4 which I own, as they are both sufficient for my use. However that does not answer your question.
Capture one for Sony Pro or Corel Paintshop Pro x8 Ultimate I have no real knowledge of. I did once download the trial version of Corel Paintshop Pro x7 and found it was not to my liking. I do not remember what put me off. At this writing I have noticed that Corel have Paintshop Pro x8 on sale, but that seems quite normal for them.
I use Corel Wordperfect x6 and have downloaded Wordperfect x8 trial only to find that there are few if any worthwhile improvements. They seem to just change the version number so that they can look like they have made improvements. The upgrade prices are not much less than the original price, so it is just extra money out for no appreciable return. I am almost sure that they do the same for Paintshop x? Pro.
Hopefully another member can give you better advice than my drivel.
