They have significantly improved their reliability and quality. Unlike some of their older stuff, they have essentially gone to more reference designs for the RF front end, as well as switching to well known SOCs.
This all allows them to go with more standard and well developed drivers, thus WiFi stability has gotten better.
There is also another huge benefit, better compatibility for 3rd party firmware. Overall, they are becoming a decent choice, as even if you do not like their firmware too much, you are essentially getting current gen SOCs, transceivers, and other RF components for a lower price.
On the other hand, this router does not seem like a good idea. It cost more than their AC3200 router, just to add a touchscreen LCD.
If it is designed for simple functions or presets, then they can get away with simply adding additional buttons. those require almost no additional cost as the SOCs used in many routers, have a massive amount of unused GPIO. They can add lots of extra buttons, or make the router more modular.
Typically, when you have your router set up properly, you don't need to touch or really look at it very often. If they want to change this, then they need to make the LCD in a better viewing position, and add lots of customizability, e.g., it better be able to display various statuses (CPU, RAM, NAND usage, along with VPN status), it should also offer the option to display other custom information sets, e.g., monitoring a local server, displaying weather.
