11700k is better for the price. Over $120 cheaper than the 12700k and it does not have big.LITTLE which means it is more compatible with older games as well as being much more stable on Windows 10.

11700k only cause ddr5 is expensive and hard to get ATM. Not too many mobo options yet for the new socket plus the $ is high for new-gen.
