Since those threads are massive, I'll point a few highlights:
R7800 - very popular around here. A lot of development being done, mainly by @Ansuel . Ethernet is questionable. WiFi works pretty well.
WRT3200ACM/WRT32X - also very popular. Marvell the company has done a lot of work that we don't have to do in getting the platform in shape. Ethernet works very well. WiFi is reported to work well. Newer features like WPA3 and 802.11w are not and will never be supported.
edit: I should mention that no WiFi 6 routers are supported yet. It's an open question when and if that will be the case.
