Which is the better pc

not really even. One is more expensive and has a GTX 1060 in it. In fact you could add a 1060 to the cheaper but better CPU build and still be cheaper than the Ryzen 1400 build.

Get the best of both worlds with a 6 core Ryzen and a GTX 1060 6gb. Use the AMD Wraith cooler to overclock the CPU to the 3.6-3.8 range if not higher and push the RAM to 3200mhz and the system will game quite well.
