Same.
UF* really handled 9th gen's incorporation a lot better with them being on pretty much every single episode of BijoGaku/HaroPro Time (I can't remember if it was still BijoGaku or not...) for a good while.
The 10th gen have just been severely overshadowed by most of UF*'s planning:
1) Aichan's graduation. Completely overshadowed the fact that 10th gen was added the night before. A lot of media focused more on her graduating than the inclusion of 10th gen.
2) Busu ni Naranai Tetsugaku. It's already hard enough for four girls to stand out in MM. nearly impossible in MoBeKiMaSu with 30+ members AND the fact that it was recorded before 10th gen was added so OBVIOUSLY they weren't going to have any lines (which mean screen time) or face time in a PV that they weren't around for.
3) 9th gen was handled much better. I admit my bias but I just like (and am more interested in on a daily basis) 9th gen better. They still feel new. They're new car smell hasn't expired yet and I can't be the only one that feels this way.
4) S/mileage 2nd gen. I know that saying they're addition overshadows 10th gen's is a logical longshot but they were handled better as well. Especially because I feel like if you're an active fan of one group in H!P. you slowly get sucked into all the other groups (I always thought I'd only be an MM fan but then I got sucked into C-ute and then Kikka (i know, not H!P but affiliated) and now S/mileage) because you watch H!P Time and stuff. And I just have to say, 2nd gen S/mileage had the whole "unofficial" members gimmick, they kinda had a single to settle into (TACHIAGA-RU), and they were included in a lot of H!P Time and Busu ni Naranai Tetsugaku. Plus, almost all of the new girls have really strong personalities with the exception of Rina.
