A knocked-out door has the disadvantage of being noisy and visible - random passersby may spot either the act or the result and alert the police, whereas most won't even spot the difference between someone using a legit key and a comb key.

The more time passes between the burglary and the discovery, the better for the burglar - if you're already two counties away when the police establishes local roadblocks these won't catch you, CCTV camera or ALPR records get deleted, phone tower (=which phone was logged in at a certain time in a certain area) records grow bigger and harder to sift through, potential witnesses forget details.
