Peach has disadvantages, but doesn't get ***** by anyone. On the other hand, she is a seriously hard counter to some characters. And yes, I do consider her to be somewhere in the top ten.
Symphonic, I'd have to disagree with you on this one. If I was in charge of this game's development, I wouldn't have added the thing to begin with. SideB was literally Peach's ONLY useless move, which is far better than the vast majority can say. The fact that BBrawl stole it means nothing. BBrawl is designed to be like Brawl, a game where Peach is top of mid, or arguably bottom of high. Then when you look at Brawl+, where the very physics of the game buff Peach far beyond those positions, why would it be necessary to implement the same buff to her? In addition, while it is my dream to have her fthrow buffed, and while I'm sure we would all like it, I'm also relatively certain that we all know that Peach does not need a fthrow buff, and never needed a SideB buff. I'd also like to say that SideB was a chancy move before, and all of the risk on the move is still there, a higher reward for successful execution has just been added. I don't even care if its gone, because high risk/reward is NOT what Peach is all about. Peach is a character that has a ridiculously safe moveset in Brawl+, and there is literally always a safer option than SideB.
