I see on the McFeely's web site, they list collated quickdrive screws for
drywall and simple drywall screws for example but don't explain the
advantages or differences of one over the other.

Yes, they are both intended for drywall, not for decks or floors. They are
not up to the task. Don't cheap out on something that requires so much
labor and will be difficult to repair in a couple of years when they start
to snap. Deck screws, Use deck screws.

Quickdrive required a special driver. You can call McFeelys for
information. They make Quickdrive DECK screws also.
