I'm 93% sure I made a post about this before, but Taylor using other people's powers better than they do is such a fun part of her character, especially since she seems to constantly be thinking "damn if only I got that actually useful power." Like, Lisa thinks Taylor would do better than her with her insight power, Taylor coordinates Cuff and Theo to make a lightning rod during Behemoth fight when neither of them had thought of that, Clockblocker with the string, ordering around like 10 people including fucking Eidolon to hold Behemoth still for Phir Se, she's always scheming and using people as chess pieces in such a way that they're not even mad because it's a learning experience. I think a large part of it is a want to be anyone but herself, which leads to her looking at other powers and considering their uses more than most people do because she just finds every reason to be jealous and justify her passive belief that she's inferior and weak. Also she's just so used to high stress fucked up situations that she performs well under pressure. She kinda acknowledges that in the chapter where she's like "what the hell why is Amy so stupid she should be using microbes to form defenses" because she realizes Amy has no experience in fighting, so she's never had a need to think about this. But Taylor is always fighting, even when she's finally safe she doesn't let herself relax, so she's used to this.
And as for wanting to escape her body and be someone else who's cooler and has a better power and isn't lame and worthless, if I recall correctly she comments more than once on how powerful Genesis is and how she would love her power, which honestly fits so well. She wants to have other people's powers because she doesn't like herself, and Genesis's power lets her create and customize new bodies that aren't her and can do whatever she wants. It's the perfect way for her escape being herself.
And then Khepri is thematically significant as always. She finally can use other people's powers, and damn she's good with them! She magnifies Sundancer's sun with Vista, she combines Ballistic and Foil, she uses every combination and interaction possible for an advantage. She can use other people's powers like she always wanted, and she stops being herself, just like she always wanted.
