Build Advice Which PC build is better?

[draguturares]

Hey, T'sH! I have those two builds. I know that the build who uses i7 is better, but how good compared to the I7 build is the one with the i5? they are both 9th gen. if I replace in the i5 build the i5 9600k with an i5 9400F, will it become better?:

You should get a Z390 mobo and a 2 stick kit of DDR4-3000 (2x8GB = $70).

If not - Here's an i5-9400F + AsRock B365 Pro4 = $190.
