Ping is transactional - it sends packet and waits for response for short time.
TCP, if it does not have a response, performs retries and waits for more time, therefore TCP is much more protected against sporadic network issues or outages.
You will not see TCP reporting problem if there is network problem for several seconds, but ping will report it immediately.
