I usually do my grain matching with a custom gizmo I've made. But then again, I'm a compositor, so I'm not so much concerned with grain as an artistic tool as I am with matching whatever the original footage looked like. I use my own grain gizmo for grain matching. More accurately, noise matching, since it's pretty rare for me to get plates shot on film these days, and the digital noise modern cameras produce is quite different from film grain, so film grain tools don't necessarily do a very good job matching it. At least that's been my experience. Edit: But yes, mostly if you can see grain in a big budget feature film, it's been added afterwards, as the production quite likely didn't even use a camera that produces film-like grain.
