I just did, have you actually tried using them side-by-side? It's hard for me to look favorably on kid3. I actually gave myself 5-10m to try and learn kid3 and a lot of what seems like obvious ways to accomplish a task like 'rename these files using their tags' didn't do anything. I even broke out the manual which didn't help/explain if there was a different mindset I need to adopt. I could manage to manually edit tags/rename file by file, but that seems like table stakes for anything that handles media files (even a file manager) let alone an application that is meant to be a specialist in that area, and we're not into any advanced functionality yet.

More generally though it's not about one specific type of tool, it's that windows and linux have been different ecosystems for decades and that has encouraged different strengths and weaknesses. To catch up would mean a lot of effort even if you're just aiming to be equivalent, or use projects like WINE to blur the lines and use the win32 tool as though the specific platform doesn't matter so much.

CDProjekt releases native linux builds.

Not really, most leave that to Valve.

That's exactly the point. They weren't, so a Linux user didn't have an option to run a native Linux client in preference to a Win32 version.

That goes back to address the original question of "But would you want to run these Win32 software on Linux for daily use?"

More than now, I own a few from the Loki Entertainment days.
