MoBrosStudios, for all of his faults (and alongside his past bouts of autism and depression-fueled rage), at least had the self-awareness and foresight to try to distance himself from reviews and work more on his passion projects despite overwhelming demand because even he knew that not only was that kind of audience not what he wanted, but that he'd get stuck in the same rut that Enter is in (hell, before Enter was even around, I think MoBros even mentioned that rut, but in regards to becoming like the Nostalgia Critic). And he eventually learned to better himself, moved on with his life and got his degree, and now does stuff like anim8ball as a hobby.
Enter not only lacked that self-awareness, he lacked any motivation and drive whatsoever to do anything, including improving his own videos. What MBS was in danger of becoming ended up being what Enter became: a shut-in depressed NEET with horribly unchecked delusions of grandeur sticking his political opinions and hot takes where they don't belong or are completely unwarranted.
