PI AF SDK vs. PI Web API for writing many values to PI Data Archive?

We're preparing for a custom development project to pull data from an external Web API and write it to PI. To write to PI, we can use the PI Web API or PI AF SDK.

 

I recall hearing that the PI AF SDK is generally better at writing large numbers of values to PI. I'd like to understand how much better the AF SDK is in this regard. In our case, this program might write 1,000 values at a maximum interval of 5m. It would be easier for us to use the PI Web API for this, so I'm trying to weigh whether using the AF SDK is worth the trouble.
