If the target has high hospitals effect, then the troop trade off probably isn't very favorable and if they have a lot of peasants they can probably train enough (including with aid) to rebuild much of their defense prior to your next wave. In a situation like that, raze bouncing probably loses you the war. If the target has high peasants, cq is a good way to keep their pop space and therefore peasants down. This keeps their econ in check and minimizes the long term threat they pose.
