How detailed is the information you receive when "something something" happens, and how are the user interface to customize settings - and how detailed?
One thing I've found over the years is that the web pages for these applications are good with the text telling you how advanced their stuff is, but very few of them show actually user interface screenshots on how you interact with the application.
For example here is Comodo CIS - Firewall - Custom settings for an executable:
And here is the same for application settings:
The biggest issue I have at the moment with Comodo is that I can not easily create a "profile" that I can apply to new applications using an existing configuration as baseline, so I instead have to copy settings from an existing application after I created a rule for the new application (Basically: A Profile can be applied on first alert, a copy-of-settings has to be applied after I already make a rule for the new app..).
