Is it better to nail into OSB or use screws?

And if it’s better to use screws, is a deck screw good enough or should I use something else?

The strength of your fastening is not in the osb itself, but in the dimensional lumber underneath.

Go through the osb to the framing underneath. 3 1/2 nail or screw.

I'll use screws any chance I get.

osb is garbage trash, use a big washer and screw and it still wont hold very well.
its just like taking a bunch of leaves and gluing them together, it has no strength except in the center.
walking in attics if you step on the conner of osb board under your a/c unit your foot breaks through and goes through the ceiling. its the worst trash ever invented, but its cheap trash, so builders love to use it all the time

This is not an osb issue as much as a shitty builder issue.

Ok, but if I step on just about any piece of unsupported flooring, like vinyl or wood plank, same result. That junk isn't supposed to be overhung, it's supposed to sit on top of framing/joists.

I would hit all of the framing if possible and use construction adhesive.

Screws have no shear strength. Nails will bend but will not shear. So out of the two nails are not only cheaper but will hold in this application better. If you were laying it flat like deck boards where shear strength doesn't matter then screws would be the better choice.
Take a screw and a nail partially sink it into a piece of wood. Then hit each with a hammer straight down on top of it. The screw will break off and the nail will bend. There are such things as structural screws but a deck screw isn't structual.

It is just a sheathing material. It's actually quite strong for its intended purpose...to resist racking. Using it for other applications because it's cheaper than plywood is where people mess up. I mean you don't use drywall as flooring.

Osb is actually amazingly strong. And yes, it’s not to be used in the case where you would step in on it unsupported.
I’m not sure what the op is trying to accomplish but if you’re adding something structural, you want to get into the studs. I am also pro-screws but ring shank nails are fantastic as well.

It will also sag in between the joists or trusses, if spacing is 24” or 36”.
