Pro Can show a file list without loading the whole archive
For 7zip-files (perhaps other types too) while File Roller cannot do this.

When creating large archives it crashes and doesn't show you any helpful message (unless you started it from the terminal you will get something like " 14858 segmentation fault (core dumped) xarchiver").
Con Doesn't show a progress UI while it's creating an archive
You have to "guess" when it's done.
Con Not in active development
Xarchiver has only one maintainer and it seems he's not working on it actively.
