Right now, the R7000 is the best all-around router at my house *smile*. Currently using it with Kong's latest dd-wrt firmware release (29230), and it is doing very well. Better wireless range/coverage than either the WRT1900AC (with dd-wrt or openWRT) and the RT-AC68P that I also have. Great piece of hardware, has been for the last 2.5 years. Still lots of spare bandwidth with the R7000 here. I'm not interested in the latest stuff yet, the clients to take advantage of "wave 2" are just not there yet, which makes it not interesting to me. I'm sure that others will beg to differ with that *smile*, but I'm pragmatic when it comes to spending $$$'s.
There are other third-party firmware releases that work well on the R7000, including XVortex's port of RMerlin's (Asuswrt-Merlin) firmware and tomato ARM. Firmware for this wireless router is mature and stable at this point, which is nice, too. Been through some rocky times couple of years ago, but that's all in the rear view mirror.
Highly recommended.
