I consent with you that many pros and cons are rather subjective and pros/cons depend on the specific use case. On the other hand, I like having a list of all these libraries with their supported platforms, license and a screenshot. This alone gives a pretty good overview of what's there. Not all pros/cons are subjective (e.g. having a GUI wysiwyg editor is definitely a pro for some use cases). Anyway, thanks for sharing your view and thanks for sharing this comprehensive overview.
Even the list of platforms is kinda pointless here, as Dear ImGui doesn't really support any platform itself. You're expected to write a glue yourself, with some examples for popular libraries/frameworks/engines being provided for your convenience (and those examples alone already go further than just four platforms listed in the article).
On the other hand, Qt is a whole framework itself which already handles all this stuff for you, which makes a lot of stuff easier, but then you're of course limited to what's supported by Qt.
Yes it is useful to have a list of everything, but I feel like I can get a list like this in about a half hour with Google. What I can't get in a half hour is a summary of the problems people have had with particular framework, or the reasons why they chose to start using or stop using a particular framework.
The picture from the beginning is very exciting and optimistic. To pick on ImGui again, it's easy to get started--but I know there are some issues with larger projects, some things that are hard to do in immediate mode, etc.
