Screws (depending on the type you choose are) are often more
brittle...esp drywall screws which are frequently used in
inappropriate situations. They're call drywall screws for a reason.
Framing nailing is just there to hold the frame together. The
strength of the system really from the sheathing (drywall or
plywood) ...shear transfer through the structure is now usually
handled with framing connectors (Simpson hardware) but good old
blocked & nailed connections can work as well.
I'd suggest using 16d "shorts" 3 1/4" x .131 (really a 12d nail)
gun driven nails for your framing.
Yeah, the right screws can be stronger in some applications but in
earth quake country or high wind areas I'd put my money on a properly
design & constructed (nailed) structural system.

And using 2 screws per stud end is an even stronger, more robust way

Now ask yourself: What would you gain by using screws over nails?
Under what circumstances would the extra expense be justified?
If rooms framed with nails were failing by the millions, then the
industry would have switched to screws along time ago. I'm going to
hazard a guess and say that most problems occur due to failure of the
wood itself, and/or poor construction methods, as opposed to the
fastener used - assuming it wasn't a plastic plug or chewing gum. <g>
You really need both. For the usual 3.5" screws an impact driver is
absolutely essential. The Makita 18V Li ion drivers are a good
choice. Using an air nailer is the fastest where there is plenty of
room to work. A typical pro tool is the Senco line using using KD29 or
ND29 3.5" 16d nails or HL27 3" 10d Ring Shank nails. The screws have
the highest holding power, ring shank nails are next and plain nails
are last but better these days than in the past with the coatings they
use. These modern tools are so easy to use these days that before long
hammers may only be used for breaking rocks. <G>
Frame with nails, there is just no other solution for any kind of
quantity and it is plenty strong. When tying into existing
building, where walls are already sheetrocked, use screws. This
keeps the hammer blows from popping the drywall nails.
Use screws only when you need a bit of extra holding power. Your
wallet, your time, and your muscles will thank you.
So what? Strength is not an issue. You might as well say screws are
prettier, or come in more colors, or are more expensive, or have an "X" (or
a "|") on their head, or come from a company with a name that sounds like a
pink unicorn. None of these have anything to do with whether screws are the
best choice for framing.
If you want to use screws, go for it.
