What is the go to for routers right now?

I'm currently running an OpenWRT fork that is getting old and hasn't been updated in awhile. I may try to put mainline OpenWRT on it, but also looking for alternatives.

Any replacement probably needs to have external antennas. I use a directional yagi antenna I made for 2.4GHz for better reception. What's the word for a good deal and feature combo when you're not a triple-A gamer? Anyone running a Linux that is not OpenWRT and worth checking out?
