I have been disappointed to date with OpenWRT's ease of setup. I remember the DD-WRT and Tomato days of 2005-2013 and it was a huge learning curve going to OpenWRT. I want to unlock the possibilities of my router but otherwise think about it as little as possible. Basically my dream is the webUI of an off the shelf Netgear or whatever but with extra little checkboxes for CAKE and guest network isolation.
In theory, a popular all in one router well-liked on these forums should be easier to troubleshoot. (Because everyone has already had the same problems.) I think OP&friends are making a compelling argument for me to go x86 next time though.
