I used to bring OpenWRT routers everywhere I go. But if you worry about performance I'd actually recommend you get a router that's supported by AsusWRT Merlin. I've had a lot of WIFI performance and range issues with cheaper routers on OpenWRT.
I recommend looking at the supported devices list, since some models have Chinese v2 models that are indistinguishable, but unsupported.
