Aluminum siding requires lots of "hands on" labor to construct a sidewall. Each piece is stapled in place and openings are cut with sizzors. Vacuum bonded walls are one piece and openings are zipped out quickly with a router.

Some "lower end" brands still use the aluminum slats, and yeah if you know what your doing a repair can be easier, but on the down side leaning on that type of exterior can cause dents and such. To each their own, but I'll take the vacuum bonded walls all day long.
