Quite honestly, I always configure Autonomous APs via CLI, even today. Though not saying the UI sucks, the GUI has improve quite a lot. It's more nicer.
The reason why I do it via CLI is the configuration is more cleaner. Regardless, configs on CLI will always reflect in the GUI so no biggy.
You have more freedom as well when you configure it via CLI.
I do recommend migrating your network to WLC based deployments. Dont worry, if the cost is your issue, Cisco has a solution for that called Mobility Express in w/c an AP can become a WLC as well
The best thing when it comes to WLC deployments is all your APs are managed in a single pane of glass. No more multiple GUIs to access. The best thing about Mobility Express is that you do not need to buy a separate WLC anymore since an AP can fill that role.
