One thing I did like about the Belkin is that it had Smart Routing. Instead of evenly multiplexing through all the channels, it gave priority to the most active channels. I only used two channels, so the other two were virtually shut down.
I'm not familiar with this "Smart Routing" as they call it, and I don't see it listed in the manual.
If you're talking about Wifi channels, most routers have an "auto" setting. It depends if you mean 2.4 or 5GHz channels. For 2.4, there are only 3 non-overlapping channels.
I prefer to do a site survey to see which channels the neighbors are using, and then I set the router to the least used channel to decrease interference.

I prefer Netgear, but the model I use (R7000) is much more expensive than the TP-Link. For the price, the C7 is a solid router, plus it's gigabit and 802.11ac.

I'd go Netgear, the D-Link/TP-Link tied for second, then Linksys and Belkin. I haven't dealt with Trend-net routers before. Everyone has a different opinion, though.
