The double (or triple) pane windows are replacements for storm windows.
Usually they are better in several ways, including more convenient and
efficient. Adding storm windows will add additional insulation as would
using triple pane designs, but likely that would be overkill for your home
and area. I would go for the low-e option. I would also make sure there is
a good thermo beak. You don't want an aluminum frame without one. Wood is
by nature a thermo break.
Since things change, I can't comment on current quality of various
makes.
