If you concede than Anakin was closer, why even pretend that getting Mace Windu to do it was an option? And why move the goal post now that you have been disproved? Def greater insight from the novelization. It's never shown. According to the novelization, and the film, she is indeed in pain. It was considered his final trial. Just like Dooku underwent his trials and still fell to the dark side. Earning the rank of Jedi Knight doesn't mean it's now impossible to fall to the dark side. You can use any terminology you want to describe it. This does not change the events of the film.
