That's right. Kuroda > Asari all the way. To be fair it's just how their personality plays out but I can't help but respect kuroda. Not once has he trashtalked anyone, although it's true that he's not too friendly.
To me Kuroda is a complete character now. He seems to have shown everything we need to know about him, spare any flashback stored for later, while Asari carries more potential to be explored. Just my opinion.
