Assumed the micro-film is stored air-conditioned and the paper isn't low
cost copy paper from the supermarket, that will moldered at least after
50 years, even if you'll store it air-conditioned.
For paper you need very expensive paper. Micro-film IMO is the better
choice, but anyway delicate if there should be an 'event' during
storage. Arnold from DE, remember the archive at Cologne ;).

They could save documents for the moment, made of very good paper, but
anyway it's not sure that those documents can be saved for a long time,
