Having not seen Ninninger past 3 episodes, I can't comment on Takaharu, so I'm just pointing out what I hear the most.

I honestly haven't seen any real complaints about ToQger being too focused on ToQ1, though...Hm. I still don't think it's the overwhelming problem people have with it, since the most common complaint is that it's childish.

As for Kyoryuger, it's all just a matter of perspective. Maybe the hype overplayed Daigo's spotlight stealing tendencies for you. Watching it on a week to week basis from the get go, I certainly got the feeling that he was in the center of things far too often, even in stories mainly centered on someone else. When I watched Kyoryu, it felt like too many episodes were "[Character] encounters issue, Daigo butts in and fixes it," personally.
Yes, character arcs were resolved without Daigo being front and center (Souji's arc with both his father and learning from Torin featured virtually no Daigo, which is why I enjoyed it so much), but to me, and a lot of others, we felt Daigo was just too shilled.
