Similar atmosphere and feeling. Both about crime solvings, each case doesnt relate to the characters but slowly you learn more about them as they go through each case. TEN solves difficult cases whereas God's Quiz solve cases through the victim's bodies etc. Plus there are some crime solving geniuses involved. More character development in God's Quiz and more romance. If you liked TEN then you will love God's Quiz.
First they are both crime/investigation shows, I guess TEN is darker than MR.BRAIN atmospherically but i don't think that's makes the point of liking one and not there other. Both feature Crimes/evidence that seem impossible and illogical. Both feature a back story of seemingly unreachable criminal with which the last ep revolves around. ( MR is Jap and TEN is Korean)
Both series have a similar style (plus, the working title for M was so close to TEN that I thought it would be a spinoff at first), both series have a similar atmosphere while TEN is actually about murder cases compared to those cases about missing people.
Also the director Lee Seung-young was involved in the creation of both series, and both are OCN Original series (OCN is a channel with lots of experience when it comes to crime series)
