The stock controller on the Air 2S is Ocusync 2 and not 3?FYI, the stock controller and the Smart Controller are both Ocusync 2.
For the Air 2, people have noted a drop in difference between the stock controller and the Smart Controller. Some people claim it is worse with the new firmware (which would be all you could use on the A2s). I haven't tested yet.
Binding, meaning one does not have to link each time the SC and Drone are started for the first flight?Instead of using "Connect". Try going directly to the Fly or Go app.

In May of 2021 DJI support told me the RC-N1 controller was O3 and the smart controller was O2. So I returned the smart controller.DJI seems to have changed their tune from when I wrote that original post. When the Air 2S came out, the written statement was that the controller used Ocusync 2 and the Drone used O3. Now that the Mavic 3 is out, DJI says that the remote will use the proper firmware for each drone and use that protocol.
Their updated statement is
When used with different aircraft hardware configurations, DJI RC-N1 Remote Controllers will automatically select the corresponding firmware version for updating and support the following transmission technologies enabled by the hardware performance of the linked aircraft models:
a. DJI Mini 2/ DJI Mavic Air 2: O2
b. DJI Air 2S: O3
c. DJI Mavic 3: O3+
