How to choose between two characters you like equally?

I've been trying to find a main on my favourite fighting games and I've managed to do it for ggst(venom) and p4au(rise) but I'm having a problem with sf6. I pretty equally love Aki and JP. I think both of their designs are really cool, they both have gameplay I enjoy a lot, and the only other preference I can think of is that AKI isn't as popular or high tier as JP but that doesn't bother me that much. I'm probably just going to keep switching between the two in ranked until I feel like switching doesn't feel right but if anyone had any ideas for how to choose they would be welcome
