13900K might not actually be binned overall better than 13700K
Intel might already be saving the best dies for 13900KS.
All cores working, good overclocker, working iGPU: 13900KS
All cores working, medium overclocker, working iGPU: 13900K or 13900KF
All cores working, bad overclocker: 13900 or 13900F
all p-cores working, good or medium overclocker: 13700K or 13700KF
If there isn't going to be a 13900KFS you are better of buying the 13900KF than the 13900K since versions where the iGPU doesn't work cannot be sold as 13900KS even if it overclocks very well. Of course intel could do artificial binning (soldering off the iGPU even though it's fully working) but most KF CPUs will probably be ones where the iGPU had to be disabled because of defect.
There was no 12900KSF or 12900KFS for alder lake and it's probably the equivalent with raptor lake. I did search for 13900KSF and 13900KFS and found nothing so it probably isn't going to be a thing. Therefore most likely 13900KF is on average better and slightly cheaper than the 13900K.

But if you want an integrated GPU you are probably increasing your chance of getting a good die by buying 13700K instead of 13900K.
If you look at the actual specs you will see that the all-core max turbo is just 100 Mhz higher for 13900K than 13700K which doesn't make much of a difference. It does not seem like 13700K will have much worse minimum silicon quality.
Code:
CPU turbo0 turbo2 turbo3
13900K 5.8Ghz 5.7Ghz 5.4Ghz
13700K 5.4Ghz 5.3Ghz
turbo0 = Intel® Thermal Velocity Boost Frequency
tubro1 = Intel® Turbo Boost Max Technology 3.0 Frequency
turbo2 = Performance-core Max Turbo Frequency
13900K 13700K
Intel® Thermal Velocity Boost (Intel® TVB) is a feature that opportunistically and automatically increases clock frequency above single-core and multi-core Intel® Turbo Boost Technology frequencies based on how much the processor is operating below its maximum temperature and whether turbo power budget is available. The frequency gain and duration is dependent on the workload, capabilities of the processor and the processor cooling solution.
Intel® Turbo Boost Max Technology 3.0 identifies the best performing core(s) on a processor and provides increased performance on those cores through increasing frequency as needed by taking advantage of power and thermal headroom. Intel® Turbo Boost Max Technology 3.0 frequency is the clock frequency of the CPU when running in this mode.
The 13900K does however use a lot more power to reach these higher frequencies so it might not actually be better silicon, just more voltage for higher clock (and more cores). We might actually see something similar with the the 13900KS, it seems like only 2 cores will reach 6Ghz with it and that might be only due to higher voltage.
So the 13900KS might not actually have better silicon than the 13900K (also meaning 13900KF will not be better than 13900K).
