Difference is most likely the price 

Mixture percentage is normally 50:50 but it's always printed on the container as you can also get products premixed. It's important to ensure correct mixture, obvious here in the winter, but also all year round as the coolant is lubricant for the waterpump.

And what is the Hyundai antifreeze mixture percentage?

Mixture Percentage is written in the Owners manual, when you get one

It will tell you on the container if it needs to be diluted and if so by how much. I seem to recall you use it straight, but as I seldom keep my cars long enough to need a change, I'm no expert.
