At this point any enthusiast router should have OpenWrt 2018 kernel 4.14+ support for CTF / FastPath / etc. This is required for 940Mbit/s up/down as more and more internet speeds are approaching that bandwidth. Also should support 75-100 MB/s read/write on USB Storage since some do that as well from OEM firmware (WRT3200ACM, R7800, R8000P, etc.) which effectively function as NAS replacement from a performance standpoint now.
Many routers support those features via OEM firmware, because of hardware NAT, good drivers, etc. and we're nearly there with open source. These features are essential for "enthusiast" in my opinion.
WRT3200ACM is nearly there on OpenWrt 2018 builds, and the R7800 is nearly there with DD-WRT 2018 builds. R7800 OpenWrt is currently behind because FastPath isn't patched in and requires manual patches. Kong (DD-WRT dev) has said the R7800 has latency issues on 4.x kernels and thus builds with 3.18 to provide this support. I've heard it works very well.
