That depends on how you veiw it.
Trixie and sunset effectively did the same thing, list of different methods. Trixie had the Amulet and separated Twilight from her friends as well as all of Ponyville. Sunset had the upper hand in that she was in a world that she was more familiar with wild while Twilight was struggling to adapt, not to mention she was separated from her friends as well, she just didn't count on her bonding with their counterparts.
If we want to go even further, Discord himself was able to pull that off as well by manipulating Twilight's friends against each other, to the point where Twilight would have lost if not for Celestia sending her all those notes. Queen Chrysalis pulled the same stunt by manipulating her into alienating herself from her friends, before trapping her in the dungeons, and would have succeeded if she hadn't made the mistake of leaving her close to the real Princess Cadence.
Starlight may have managed to pull it off, however the consequences for her actions were completely unknown to her, which can't be said for the previously mentioned villains since they intentionally went out of their way to make sure this was the case.
however in each case, the reasons for the reformation was somewhat different, Trixie only partly reformed yet still held a bit of a grudge against Twilight, as evidenced by the episode "No Second Prances", Sunset had to get nuked by the rainbow laser in order to finally get it to her six-goal how selfish she was being, Discord found out that he genuinely valued Fluttershy's companionship and chose it over having free reign to do whatever he wanted, though he does still go out of his way to mess with them every now and then...
Starlight realized exactly how badly she was screwing over the rest of Equestria the moment she saw the Ashlands timeline and even presented herself before Twilight and her friends for any punishment they deemed fit, something none of the other villains have done upon their own reformation.
