I asked the same question some time ago. Never did get a really satisfactory
answer.
Maybe the Homeline series was introduced to compete with the less expensive
GE breakers, and similar.
Maybe the QO are better built, but how?

I needed a SquareD 15a/15a breaker. The local store had three designs for
$7.50 (homeline), $12.80 (QOT), and $16.50 (QO). Sadly, my box required
the
$16.50 kind.

Other than that they can get it, is there any reason for the radical
pricing
differences? Is my $16.50 breaker somehow better than the $7.50 kind
