IMO having fragmented tables, assuming they have less then 10 extents is
less worse (with the stress on *less*) than having a highly fragmented free
space.
Currently, the consensus is more and more going in the direction of using a
default storage clause per tablespace, initial and next extent equal, and
forget about specifying a storage clause on table or index level.
In this case all extents will be uniformly sized, a feature that is also
available in Oracle 8i locally managed tablespaces.
