Newegg review star average is about the dumbest metric I can think of to judge a product. (sorry, brutal truth only here) Did you at least filter to verified owners only? Sure, read some reviews to get an overall feel for potential gotchas or flaws, but other than that they are basically useless noise.
Go asrock for bang/$, the tachi and pro are literally identical save the 10Gbe port and color scheme. (same pcb, they even said as much) FWIW, if you actually need fast networking go with optical 10/40 cards off ebay and save $$$ because copper 10Gb networks are a triple-fail: dead end old tech, cost more to build and use more power.
I have seen the pro at the same ~350 after rebates/promos during a few recent sales though, no reason to skip it then.
2018: at 120 Zen cores and counting, so pretty much done with intel on the desktop.
E5 2696v4 22c44t 2.2~3.7Ghz - The last great gleam of the pre-nerf HEDT era.
E5 1680v2 8c16t 4.5Ghz - "Yes Virginia, there were unlocked xeons" /weep for them.
