I find that my Synology router has been rock-solid and extremely performant. I have the RT2600ac and have been quite happy with it, and it has a nice web interface that you can configure automatic updates on, so it can even be distributed to people who aren't quite as network savvy.
I recently bought https://mikrotik.com/product/RB952Ui-5ac2nD-TC. It was much cheaper than my previous stock Netgear router but it's orders of magnitude better.
This live demo of their web UI at http://demo.mt.lv/ and http://demo2.mt.lv/ should give you a good idea of what you get.
