As someone with moderate networking experience in a Cisco environment, and having set up Ubiquiti products and a pfsense router, MikroTik tops the cake for worst learning curve. I wasn't even trying to use it as a router, I just wanted a basic L2/L3 switch with some VLANs. It's set up now and I'm happy with it, but prepare for lots of trial, error, and head scratching.
