Previously I had, over the span of 18 months, an ASUS "Dark Knight" (whose 5GHz network slowly faded and then _disappeared_, apparently a known issue), an ASUS RT-AC66U (frequently just choked, requiring a reboot), an a Netgear Nighthawk AC1900 (same, and also issues with unstable wifi).
By contrast, the Mikrotik has been rock stable for the time I've had it (6 months). I also love the WebFig UI. It's a lot more technical than consumer routers, but it's responsive, consistent and doesn't hide any technical details from me. I don't need 90% of the RouterOS features, but I know that if I needed something obscure, I could set it up. You basically get an industrial-quality Linux-based router/switch OS for almost nothing.
(I do like the fine-grained metrics, though. You can get bandwith and connection data not just per interface, but also per NAT rule, for example.)
