It would depend on the type of data contained in the SQL databases - for
example, if the database is primarily records vs binary blobs.....

Unfortunately it's kind of hard to say "compression XYZ will always be
best for this usage", since everyone's needs are different.

As a general rule of thumb, bzip2 is better than gzip for compression,
but worse for speed. (although with modern CPUs, it's less of a concern)

That's more a tar issue than a compressor issue.
