Yes — what 7zip has going for it is that it’s free, good format support and probably usually slightly better compression ratio. But that’s basically it. WinRAR is a very competent archiver tool where you might prefer it for many reasons. One annoyance I have with 7zip is its surprising number of non-implemented features. Just today I tried dragging a file to replace an existing and got the message “access denied”. That was like code for “not supported” because deleting the file first worked. Sometimes you do get sudden “not implemented” though for the most basic operations even after all these years.
I’m not dissing Igor Pavlov. He’s a very skilled developer as for compression format development. But he ought to get some assistance on the archiver software front.
And very annoyingly, 7zip has had for years a race condition where when you open a file inside an archive, it extracts the file in the temporary folder and then... it deletes it before the associated application manages to load it. It is hit and miss when it works - often it does, but then for some reason i haven't figured out it just deletes the file. And related to that 7zip extracts only the file you double click on, so e.g. it doesn't extract any data files an executable might need or images or subpages an HTML file may refer to.
I have both installed and in my experience WinRAR is by far the better tool when it comes to handling archives with the main exception (and the only reason i have 7zip installed) being that 7zip supports extracting from far more archive formats - including disk images (i use it all the time to extract files from VirtualBox, PCem, etc disk images and seems to support a variety of file systems too).
