On a modern Win10 based bench 1% lows are pointless, since Win10 is still plagued with bizzare DPC issues and the entire WDDM is hot garbage on top of it all.
As for the 10600k, it's a perfect tweaker/OC'er chip. For the average person building an ultimate top fps gaming machine without too much tinkering or OC knowldege a 10900k makes sense. I literally got a 9600k vs 9900k from MicroCenter along with a OC friendly Z390 Aorus Master because the first thing I would have done with a 9900k is disabled the HT (or SMT, as I do on all my pure gaming machines) and probably dropped a core or two to help along with the heat (something I did on a voltage hungry Ryzen gaming machine), ending up with a 9600k anyway.
If I was a "newbie" to OC ing or just didn't care or even never entered a BIOS or UEFI in my life (like many newcomers these days, who wouldn't even know how to disable HT with a Youtube instructional video holding their hand) then 9900k/10900k makes sense. Otherwise, 10600k is probably the best gaming chip you can get now.
