Not necessarily - just that GNUtar is not ubiquitous and there might
be more concern about strict UStar format compliance.

I don't think so - I'm fairly sure I've seen GNUtar complain about bad
headers, say 'skipping to next header' and then find something. It
won't do that if you used the -z option because you generally can't
recover from errors in compression. But, I've never seen a tape drive
recover from an error and continue past it anyway so in practice
that's not going to matter. If you are concerned about errors, keep
more copies.
