It will depend on soil chemistry (PH) and physical abuse.

The literature pretty much agrees no difference at all.
Another point -- the only reason to bury radials is a mechanical one. They
work fine laying on the earth.
What you MIGHT see is interaction between your 80M and 160M antennas -- that
is, the 160M antenna may act as a parasitic element to the 80M antenna and
modify the directivity of the 80M antenna. I would not expect the reverse to
be true.
