Cons
Con Updating to a new version overwrites configuration settings
Colors, fonts and autojoin behaviors may be customizable, but backing up the settings prior to updating the software is imperative.
Con Crashes when trying to download search results (on Ubuntu 16.04)
Con No GUI
Actually a plus for some, lower memory overhead.
Con Gives little direction upfront
Actually, Irssi.org has it's own GREAT documentation for new irssi users. Inline /help options are pretty well documented.
Con Cryptic configuration files
