Teaching twenty kids of wildly different levels is always going to be harder that teaching a single kid, so parents have a great advantage by default.

Yes, there are educators who are so great they can teach all 20 kids amazingly well, but those are super rare. Most likely kids who are learn much faster or much slower than the rest will be left behind. If you child is in this group, it's better off to stay away from public school.

(It could have been much better if there were advanced classes, "magnet" schools, etc.. but in many states those programs are being cancelled and everyone is being forced into rigid programs.)
