I would get the RT-AC68U. The RT-AC87U is so new that few clients even support it's maximum capabilities.
Awesome xmas present!
The wifi seems to be better on 87U.(well duh its faster than 68u)However, the signal strength was a bit better too.
Interesting you say this, that wasn't really the impression i had got from reviews.
I have been pretty happy with my N66U, but its wireless range drops off a bit at the furthest point of my house, and i have been tossing up on whether to get an AC68U which goes for the equivalent of US$175 here, however there is a deal on Sunday where i can get the AC87U for US$203.
I'm tempted by the 87U as it's design is considerably better than the AC68U (particularly for where i need to put it). If the wireless range actually is a bit better too, that may just push me over the edge.
