And who says Shepard will keep maintaining power? I would argue that having Shepard's memories and morals would give the new catalyst a much more flexible viewpoint, so if the galaxy is better running by itself, it will leave.
Unfortunately, the Shepardlyst's speech implies that the Reapers aren't going anywhere. Claiming that the Shepardlyst would just make them leave enters the realm of headcanon. I have nothing against headcanon personally, since using it is the only way for me to feel comfortable with any ending at all. However, as soon as headcanon enters the picture, what happens in-game is no longer relevant.
When I examine the various EC endings solely on what each presents, I still prefer Destruction (but by a very narrow margin). The galaxy is free to determine its own fate without Reaper influence, and I find the cutscenes to be much less creepy. With headcanon, Destruction wins hands-down, since I remove the genocidal element.
Similarly, you may prefer Control as it is presented in-game, and you might like it better when your headcanon sends the Reapers off to Andromeda or whatever.
