Why Firewall Reject Rules Are Better Than Firewall Drop Rules

"Most firewalls come pre-configured to quietly drop traffic rather than reject it. But what’s the difference between the two and is it truly better to drop instead of reject? If you have never given this question much thought, the answer might surprise you."
An interesting POV. I've been dropping packets all my life (just like 99% of firewall admins), but Chris's explanation makes sense. Some of his statements are trivially true, while others would need some investigation to prove or disprove.
