500,000 won La Mer cream vs. 4,000 won Nivea cream, which one would you use?

It is said that the 10 ingredients have many similarities when comparing the two products.

Would you rather buy a La Mer cream in the 500,000 won range, or a Nivea cream for 4,000 won? Given the huge price difference, there must be a big difference, right? I'm curious.
