But I rarely see anyone ever use "===" for comparing strings. Why not? Wouldn't that be more accurate?
It's more accurate if you need it to be. Most people utilize PHP's ability to blur data types. You can compare "4" and 4 and they'd be equal. This is useful in certain situations but dangerous in others because people get complacent. If you know what you're comparing will always be a string and it always needs to be a string, then use the identical operator (===).
