I may be weird but I use both Ark (default archiver in KDE) and 7-zip in wine.
The reason is that 7-zip has better compatibility with some file formats but most importantly, Ark can't extract files with unicode file names from some archive formats (including tar!). This problem has been known for years and affect many other linux archivers, it's a pain in the ass.
Yep, it's unofficial but the tools are p7zip and p7zip-gui. Confusingly, there's also PeaZip (which uses the 7zip libraries) and has no relation to the former.
p7zip doesn't seem to be maintained anymore, 2016 seems to be last update (direct link to source forge from the 7zip website).
However a direct official cli port seems to have been created. Not sure if it can be installed through a repo, or if it has to be downloaded from the 7zip website.
I saw some older threads saying it wasn't maintained anymore
