OpenWrt One is based on Banana Pi anyway. And it comes already assembled, with the Luci GUI working out of the box, etc. In other words, it is a nice package for those who DON'T want to any screwdrivers to be involved just to get it actually running in your home.
I always wanted to try OpenWRT but was put off by the necessity of doing hardware modifications to stock routers to gain root access. So naturally, once I found out that they were releasing some official hardware for OpenWRT (the OpenWRT One router), I ordered it as soon as possible. The router is excellent! It solved my bufferbloat issues and much more.
