Netgear, Asus, D-Link... To be honest, it's all the same thing when it comes to wireless reliability. If you buy the latest product from any manufacturer, it's usually based on new technology that hasn't been as extensively tested as the previous ones. Wireless is hard to FULLY get right, because it involves dealing with external sources of interference, and also compatibility with a lot of different types of wireless cards and antennas, not always running up-to-date drivers (as laptop manufacturers rarely bother to update these on their website).
The issue became more prevalent when wireless started to become one huge experimental farm with the addition of 802.11ac. A lot of optional features might or might not be implemented, and when they are, they aren't always fully tested. Broadcom's band-steering technology as used by the R8000 and RT-AC3200 is just the latest one.
That's why products that are labelled as "business class" tend to use what appears to be "old technology". The home/SOHO market tends to provide a nice set of "lab rats" for testing new technology, and assisting (...) in debugging it. Once it reaches a sufficiently stable state, only then they start appearing in business class products.
The bottom line isn't to pay a premium to go with business class products, unlike what some people claim. Just get a SOHO product from a previous generation, and you should be good.
Getting those latest product is fine, provided you are willing to take the risk, and accept the fact that you might need to spend quite some time trying to get it to work right. If you want a "plug and forget" type of device, best you go for an older, more mature product.
Tim often preached about this in the past, how people buying bleeding edge products should expect to... bleed. It's not the fault of one singular manufacturer, it's a widespread problem.
