agreed, even if she falls from being one of my favorites in Berryz i still have respect for how hard she works to get stand out and entertain. and i was even rooting for her to keep it up at the beginning, when she started being the prominent one on TV shows. but she now brings that chara to daily H!P dealings (concerts, the Mobekimasu events, HaroPro Time, etc.) so it's like the old Momo has been lost completely. there's no balance.
Sayu, for example, had a very strong TV chara as well, but in H!P stuff she was still the same old Sayu. it was a lot easier to accept the over-the-top narcissism on TV because you see her tone it down everywhere else, and then eventually on TV it became less about her self-love and more about how she can improvise clever ways to put other people down! now that chara was/is funny, and is balanced out by the sweet/kind/kouhai-loving chara she gives us in every other situation. ^-^
Momo is more acceptable in Buono! because Miya never lets her get away with anything lol. cuts her off before she can finish and all that. but if anything, that just makes me like Miya more.
