Should I use Mako or Nonon?

So luck of the draw, I managed to get both units. I really like both characters, but I feel like I should only have one on my main team; so far it consists of Misaka, Okarun, and Sanstone (I know it’s not exactly meta or whatever, but they’re characters I like. Though imma replace Sanstone eventually with another crossover rep. The other two are staying though. Also I’m still a noob at this lol).

Between Mako and Nonon, who would better fit what I’ve got so far?
