Yes, I do. But don't forget the 'special circumstances' of the upgrade listed below.
Not only was I able to test the RT-AX88U before I had to make a decision, but I was also able to be 'guaranteed' to sell my RT-AC86U for a good price too while the RT-AX88U was on a substantial sale discount.
The person receiving my RT-AC86U wouldn't have been able to upgrade without buying a known/good used router (and they really needed to upgrade) and I wouldn't have been able to buy and hope to sell my router all while hoping the 'AX88U was worth it too.
In addition to the benefits listed in the post below, I am also enjoying the faster responding GUI, and the better-behaved USB ports too (more compatible with different USB drives and even USB 3.0 mode with little impact to the 2.4GHz usage I require).
With double the RAM and 4 cores, it is the fastest responding router I have used. With amtm, Diversion, Skynet, YazFi, and Unbound (and more) scripts, it is even more secure and faster too. Not to mention the 8 Ports that are put to good use too.
This router reminds me of the classic RT-N66U so long ago. A workhorse that is also a racehorse with RMerlin magic inside.
