If I can source an enterprise Cisco/Juniper/Arista ASIC switch that is 1) rock-solid 2) full featured 3) cheaper - which I can - there is unfortunately no rationale where Mikrotik would be applicable in any professional project of mine.
With that said, I love Mikrotik for what it is: it is very approachable and it fills a niche. I believe it has added a lot of value to the industry and I'm excited to see their products mature.
You're delusional on price. I wouldn't touch severely overpriced and backdoored American switches with a 10-foot pole! Meanwhile, MikroTik just released a 400G switch in under two grand. To buy Cisco/Juniper/Arista with your own money in 2025 you have to be super rich and super stupid. And I say this as a guy that buys 100G stuff from Xilinx.
Based on the lldp messages I see across dozens of countries, the majority of business isps globally use mikrotiks at their edge.
