Both appear to have powerless noodle bats despite some previous flashes of power.
Both are good receivers/throwers.
Kirk may be the better receiver. Moreno has the better arm and obviously better baserunning. Moreno probably holds up better with full playing time compared to Kirk.
I'm fine with Kirk sharing time with Jansen. I just don't want to lose Jansen and end up with Kirk as our primary catcher.......
