>The biggest problem for me about the ISP routers is their sheer size, they probably make them big so that they seem "powerful" to the average person and he chooses that ISP believing that their router provides superior Wi-Fi.

Size is not just for fun, if you have mu-mimo capable device with multiple antennas you need distance between them. Same with the spider like gaming routers, its not just aesthetics.
