Also, Mikrotiks are behind even mid-range consumer devices in Wifi. You can get 4x4 ax wifi from Asus and it's going to work great.

Mikrotiks are very stable and reliable but not that fast.

Of course, it depends on speed of your internet connection. You don't need 4x4 wifi if you have 100 mbps internet, but it's kind of annoying to pay for 500 mbps cable (because they don't offer anything slower) and be bottlenecked by wifi.
