It has serious updating issues however requiring you to completely setup the router every time you update and the update process is entirely manual. I like FreshTomato I have used it for some years but the wifi performance sucks and the constant clearing of settings just grates over time.

This is something commercial routers get right, updates keep your settings. This requirement will cause you to delay if you use any of the complexity of the router and that leaves you open to attacks. IMO its not a great choice today due to this one fatal flaw.
