What with Gary Key of ASUS posting the 2678 firmware for the RT-AC87 to the forum, 87U/R owners have gotten another update in a very short period of time. I can't remember seeing this kind of dedication from ASUS with my previous AC-66 router (I can't speak for the AC-68 as I haven't owned one).
While there are still reported issues with a few features (namely the new QoS features, which I myself have not enabled or played with), I have seen great strides since the 1179 firmware that the unit had at release. I'm getting excellent wireless performance, and stability issues have stopped for me. I have no regrets in buying my AC87 other than that as I just passed my WatchGuard certification exam, I can now get a deal on one of their units (which is a great firewall/router, but its wireless can't match the ASUS).
I will agree the rt-ac87r has issues (as all do when just released ) BUT all that I do with it are minor and Asus keeps pumping out updates. Also I had way way more major problems with the rt-ac68r that took months to fix. But for what you do with it, if it does not work then you either wait or bail, but for me this router so far is just outstanding (with what I use it for, so far).
Best of luck.
Edit:
I just noticed your other thread, and out of your list I don't get or see all them problems you listed. But I am using merlin newer firmware, have you even tried that?
