Ok correct me if I'm wrong, but it seems that the Super Talent F3200 kit smokes everything in terms of overall performance and at the same time, costs only 129 bucks. Seems like a bargain to me.
Higher RAM speed requires a lot of tweaking in order to make it go faster than lower speed memories because of LATENCY. @ 3200, the default tRFC is usually around 400. At 4000mhz, the motherboard automatically sets the tRFC to around 700. Higher tRFC causes higher memory latency, which is why the 3200mhz is usually faster than higher clocked memories. Once you manually lower the tRFC, higher speed RAM such as 4000mhz can beat any 3200mhz RAM at tight timings.
tldr: Newbies are better off with DDR4 3200mhz and use XMP settings since they don't have to tweak the hell out of their RAM. They may lower a few primary timings until they're satisfied. RAM tweaking is arguably the worst overclocking experience and can be a nightmare for inexperienced users.
Higher clocked memories (4000MHz+) are for enthusiasts who are willing to lower all of the subtimings until they are stable. XMP settings and lowering the primary timings for these products is not enough. The end result is usually faster than RAMs at lower speed once you balance out clock speed and latency.
