Don't know what this discussion is for?
RAR, ZIP, 7Z or whatever, they all are doing their best.
Having 1 735 512 Bytes or 1 386 999 Bytes isn't so much important in time of fast internet.
I'm mostly using WinRAR, it's fast, small archives, it's secure and rebuilding a damaged archive is really working sometimes...
May be I'm on wrong way, but why should I change my archiver?
