They are likely to choose reverse osmosis because it addresses a wider range of problems, including bacteria.

Reason: RO membranes physically remove bacteria and many other contaminants (dissolved salts, organics), while ion exchange targets dissolved ions (hardness, specific metals) and does not kill or reliably remove bacteria.
