I know that this is, to some degree, an anti-Netgear forum, some of the most frequent posters would rather eat dirt than recommend Netgear products. However, Netgear hardware really is great if you read reviews and choose carefully...I've got the R7000, R7800, and Orbi, and all of them have been great. No lack of support from Netgear, and the R7000 in particular has several varieties of third-party firmware support. DD-WRT is working on supporting the R7800 (Netgear's firmware is working well for me for the R7800), and the Netgear firmware for the Orbi has also been great so far...Netgear is committed to doing some enhancements for the Orbi, as well.
At any rate, Asus is not the first place I'd look for a wireless router, etc. these days....I do look at Asus products, but Netgear also has good, well-supported products. I know that some have dived into some of Netgear's less well-advised products that have fallen by the wayside, but there have been some Asus products that have done that as well. You just need to read some before jumping, and understand both your needs and the products you're considering. As with most things networking-related. The latest product is not necessarily the best one for you, so just be careful to do your homework.
