If the vast majority of the screws are drywall, then it might be worth
considering a screw gun. Otherwise, a good quality 18v drill driver
would be a sensible investment and would produce clean and
consistent results.

You are maing that up, as you have never used a drywall drill.

I did not say "drywall drill".

I own a Senco collated screwdriver.

This is exactly the correct tool to use if driving a large number of
drywall screws

Matt the OP said: "7000 screws ranging from drywall to 4 inch". That calls
for an Impact driver.


It is more likely for a project of this nature that there would be a
significantly larger volume of drywall screws than there would be 4"
screws.

Typically, one does not use 4" screws for attaching drywall.


An impact driver is completely unsuitable for drywall screws because
there is not the level of control required to avoid either leaving the
screw proud of the surface or pushing it right through the board.

Impact drivers have no clutch in the way that a conventional
drill/driver does and the only controls are the amount and time of
trigger depression. This means that the operator must gauge both
accurately for every screw. This is going to become very tedious.

A screw gun gives the easiest and fastest way of putting in a lot of
drywall screws. I know, by the way, because I have done it.

Failing that, the 18v drill driver is the correct choice for the
purpose requested.
