GL-iNet offer a user-friendly interface for general user,and keep original luci interface for advance user.
Also,they enabled hardware accelerate feature ,provide remote access (both app and web).What's more better is GL firmware is compatible to original openwrt,allow you install ipk as you want.
It's exactly what I need,but GL hareware cost $99 or more,so it occurred to me that building a GL firmware for other similar device.
For this time,I choose to port to qihoo 360T7(AX3000).It's ISP custom device,which cost $20-$25 and provice 4 gigabyte eth port.
