I only use Clear Linux. The only problem I had were related to a release a few weeks ago (or months?) with broke the desktop environment. But after that, no problem.
Not sure about the cons or pros. It’s different for everyone, we all have different requirements. Maybe tell us about what software you use and things like that to get a better idea.
The only cons that apply to any Linux or not macOS/Windows is the availability of third-party apps and things like that. But if you are already a Linux user, then you won’t have any issue, I think.
