An excerpt:
I use Ksnip https://github.com/ksnip/ksnip which is not in the list, though some users did mention it in the comments section. It's available in different file formats such as .deb, .rpm, and .Appimage for Linux. It's also available for windows and mac. I find it to be very good; tons of features and a nice interface. The one downside, it's that taking screenshots of a selected area doesn't work in Plasma Wayland https://github.com/ksnip/ksnip/issues/660,Some of these tools are not only meant to take screenshot, but also to modify the picture, adjusting the borders, depth, color and a lot more while capturing screen of a particular application or a whole window.
