Here's the thing with the broiler. It won't brulee everything evenly. So you will end up with a few burnt edges while at the same time getting a few perfect centers and then a few that just won't be done. If you want perfect tops get a kitchen torch. If you don't mind imperfection just use the broiler. In my attempt to get as close to perfect as I could with a broiler, I ended up with a few more toasty edges than I would have liked. Still delicious though, kind of like burnt popcorn.
