What's the use-case for WinRAR in 2023? I switched to 7zip over a ~decade ago and never looked back. Although I also have fond memories of using WinRAR as a kid and always felt thankful for the unlimited trial.
For me, support for archive recovery record, which 7zip does not support.
I seen this mentioned a few times in the thread. While true, there are other tools (with more control) for creating recovery data, notably, parchive[1].
