Tiana, once she got past her emo phase did pretty good out of StrikerS. She ot befriended, her shit got sorted out by Signum and later she owned three cyborgs at once on her own using intelligence as opposed to brute force like everyone else.
That aside though, I've always seen StrikerS more like Mai-Otome.
Hugely expanded cast with our favourite characters from the previous series now aged and in positions of power, their screen often reduced for the new generation. Everything is different and the overall product isn't as good as what it used to be (which wasn't very deep in the first place).
