I don't think there is any such general consensus.  Are you reading
something that favors Solaris/*bsd over GNU based systems?

I doubt if they are as well maintained in linux distros as the GNU
tool set, particularly in terms of having recent fixes backported into
the versions carried in enterprise distros.

I've never had any doubts that current GNU tar would extract archives
made with it 10+ years ago - in fact I'm fairly sure I've done that.
Or that I'd be able to obtain a copy of it in the future.

It shouldn't matter if you don't use either of the version's
extensions, and for archiving you probably don't need them.  For
example, star and GNUtar use very different concepts for incremental
backups - star is sort of like dump and must work on filesystem
boundaries where GNUtar's --listed incremental needs a file to hold
state but will work on arbitrary directories and can span mount
points.  But for archiving, you probably only care about the maximum
size of a file it can handle.
