Two fallacious assumptions here.

You assume every simple question has simple answers.

You assume we are here to do your homework for you.

The answer you're probably looking for is "vernier acuity."

But I don't know anyone who uses vernier acuity in the refracting lane or in
school screenings.

"Best" might mean "easiest to understand."

"Best" might mean "most universally available."

"Best" might mean "hardest to fool."

"Best" might mean "most sensitive."

"Best" might mean "static" or "dynamic".

"Best" might mean "central" or "parafoveal" or "peripheral"

All those criteria demand different answers.

When ordering up a glass of knowledge, please specify your flavor.

Do you prefer yours with the floating turds, or without?

Don't you realize that there are trade offs between different kinds of
sight and that it is not possible to get the BEST vision for
simultaneously for each kind of sight?

Would you move your eyes to the side of your head to make your vision
better for one kind of seeing but make it worse for another?

It's like asking, what is the best kind of car? Do you mean speed, or
acceleration, or passenger capacity, or color, or hauling capacity, or
performance, or comfy ride, or fuel efficiency, or fuel type, or fuel
capacity, or electronic gear, or navigation, or hight of ride, or
distance per fill up, or longer warranty, or reliability, or least
likely to be stolen, or visibility, or backup assistance, or, or, or, or
...?

Perhaps you can see, trade offs exist in almost all choices and getting
the BEST vision depends on what aspect of VISION you want to be BEST in
while understanding that you will have to compromise on other vision
aspects.

Can you afford the Gas and the Tires that frequently need replacement
and additionally the insurance? Heck, if someone GAVE you a Ferrari,
the government would likely force you to pay gift taxes and if you were
gifted enough money to deal with the tax issue, I doubt you could afford
the maintenance and insurance.

I was watching a car show one evening and the host was test driving a
very fast car. He wanted to take it as fast as it would go but the
tires at that speed would only last 10 minutes and cost a significant
sum of money.

The BEST car for you is likely something else, perhaps a bike.

What do you mean by "measure of eyesight" and what do you mean by
"best".

Do you mean acuity? or refractive error? or ability to differentiate
between two similar objects? or ......

By measure of eyesight I meant, what's the best way to measure how
clearly you can see.

The most accurate measures would be a vernier type visual acuity test
and contrast sensitivity test. These are not commonly available
outside of research labs.
