Mikrotik is not a mere replacement for plug and play routers such as TP-Link and the like. It's a very advanced device offering countless networking features, including multiple VPN server options, advanced Layer 2/bridging/switching features - VLANs, nested VLANs (Q-in-Q), VXLAN, spanning tree protocols (STP, RSTP, MSTP), 802.1x authentication, bridge-based firewall and bridge-based NAT, data center bridging (a.k.a. "lossless Ethernet"). Advanced Layer 3 features such as BGP, policy routing, traffic shaping, VRRP, hardware layer 3 acceleration. Then containers, matter/thread protocols, mesh networking, advanced wi-fi features such as centrally-managed network (CAPSMAN), multiple/virtual access points, hotspots, and many many more. Advanced firewall for both IPv4 and IPv6. On top of that scripting, SSH server, NTP server, DNS cache. API client for advanced integrations, and built-in scheduler, packet sniffer for troubleshooting, safe mode for automatic rollbacks of recent changes in case when the admin gets cut off due to a dangerous change. It'd be really hard to enumerate all that RouterOS offers.

And all that is available from tiny home/SMB office devices starting at 40 USD, through dedicated wireless point to point bridges, to a big Ethernet switches/routers with 400G interfaces.

Of course it doesn't compete with high end NVIDIA Spectrum-X, Cisco or Juniper, but is good enough for 95% of networks.

It works great as a plug&play home/office router, too thanks to Quick Set, but for more sophisticated setups, a knowledge of networking protocols is mandatory. The more fancy setup, the more in-depth knowledge is required. Just like with programming and all stuff in life.

One of their newer APs has thread radio. That is the best idea anyone has had since the mid 90s.
