From my understanding, the "changes" to the AAW stat haven't been proven to exist yet. I assume that's what you mean, and you're not talking about the changes where they can use HHs and such.
But even if they had changed the AAW stat to make it work, the reload stat would still be more important. This means you would want to use regular gunners classed to reload. If you want to use the Pom Pom guns, then the delay classing mentioned above would be the way to go.
