1) Their main push seems to use a thick client for admin which is a big no to me, otherwise the web ui in theory looks ok-ish. 2) Looking at their cli guide, it was cryptic as hell to me, and I deal with everything from cisco, arista, aruba, juniper, fortinet, pan, whatever from a cli or gui.
This was mostly confirmed a few weeks back, another old network engineer friend of mine hit me up asking if I've ever dealt with Mikrotik, and said no, but I knew where he was going. He'd screwed with it for a day or so supposedly just trying to make some L3 vlans, and finally a day or so later told me he'd made it work, but has never dealt with anything so terrible to configure from either gui or cli after having tried both, and he's another 20yr+ network engineer like me I trust not to be stupid.
That was all I needed to hear for future consideration.
