How to Buy the Best New Router (Thought Process)

So I bought another new router… hopefully this one is for keeps. The ASUS sucked… here’s why I replaced it with a gigabit tri-band router from TP-Link: the Archer C3150. Also, I explain why I didn’t buy the eero, Luma, Starry Station, Nighthawk, Google OnHub (actually I did buy it, but then canceled that order) and a few other routers.
