Tire Comparison

Is there a big difference between the Ventus S1 Noble2 H452 and the 462?
The price for the 452 is in the 420,000 KRW range for 4 tires, while the 462 is in the 540,000 KRW range. That is a difference of about 120,000 KRW.
The tire spec is 225 55R 17
for a K7.
The installation shop says there isn't much difference and suggests choosing the H452, but I am curious.
