Best free file compression software in your opinion?

What you will actually find is that there is often very little difference in size between the normal and ultra compression level settings, if you compare the final archives size for size, then 7zip is faster.

No 7zip is not faster.

I downloaded, reinstalled 7-Zip 19.00 and benchmarked compressed Justice_RTX_Demo folder.

Here are the results:

Compressed 3.71GB Justice_RTX_Demo file which used Zip for DOS archive, WinRAR took 2 mins, 11 secs to created solid SFX 3.36GB rar file with Normal compression method while 7-Zip took 2 min, 28 secs to created solid SFX 3.34GB 7-Zip file used Normal compression method.

The final archives size for size are negligible, it showed 7-Zip is actually slower.

WinRAR is faster again.

Not surprised to see 7-Zip 19.00 still got data error after tested extracted some files.

Now uninstalled 7-Zip 19.00 again.
 
As I said, you are talking about negligible differences on only a single archive, which vary based on which platform and hardware you are using.
 
I rarely actually compress things, it's mainly for extracting files from downloads. I used winrar for years and then switched to 7zip. I can't actually recall why I switched.

Might do some testing see if there is an appreciable difference. :)

Very interesting benchmarks that PeaZip with ARC has the highest compression ratio in the world.

I installed PeaZip 6.7.2 and reinstalled 7-Zip 19.00 to benchmarks all 3 archives alongside with WinRAR 5.71 beta 2 to decompressed and compressed Nvidia driver and Justice_RTX_Demo at all levels and I now completed the tests.

Wow I am very impressed with PeaZip, it took incredible 32.5 secs to compressed 566MB Nvidia driver at default level that put WinRAR to shame which took 48 secs to compressed 578MB at Best level and 7-Zip took 1 min and 21 secs longer to compressed 555MB so PeaZip can compressed 558MB in 45 secs at level 5. I am amazed to see PeaZip managed to compressed 3.49GB Justice_RTX_Demo in just 6 secs put WinRAR's 31 secs Fastest level 3.64GB to shame and PeaZip ARC can compressed Justice_RTX_Demo farther with 3.08GB in 7 mins and 57 secs at level 9 than 7-Zip managed 3.20GB in 4 mins and 17 secs at highest level Ultra.

I will keep both WinRAR and PeaZip and get rid of crap 7-Zip forever.

I think everybody should uninstall 7-Zip and install PeaZip!

This is just childish now, it's completely down to your configuration settings, 7-zip took longer because it shrunk the archive more than Winrar. When it comes to compression you get rapidly diminishing returns, as the archive size is reduced further the time to compress it increases exponentially. 7-zip has a plethora of compression algorithms that can be selected in addition to the speed modes.
