Electing a representative who will make decisions on your behalf is what representative democracy is.

In a representative democracy, do you have a say, control or checks in what decisions those representatives you elected make? Or do they do whatever they want and, tough luck, wait 4 years? Or do they do the opposite of what they promised and tough luck, 4 years again? And the same 2 parties which are essentially the same can get elected and none else, so... tough luck in general?

If you have a system that consistently makes better decisions and leads to better outcomes for more people across countries and eras, I'd be delighted to hear it.

You know, China's system made wonders. Maybe everyone should follow it? No other system achieved such an unprecedented economic growth and lifted so many people out of poverty. Freedom? No need, you don't have more in the US anyway. US is just better at PR towards some of its own citizens.

Dismissing criticism about our system,in which the officials just do whatever they want without checks and lie every four years to keep doing it, by saying "tell me a better system", implies you have given up. Good for you, but at some point the "best system in the world" was monarchy because the question "can you tell me a better system" had no answer either.
