I quite like that it comes with command line util so it's easy to sync up changes with one command.
It's also dirt cheap if you have modest traffic. I doubt I'll spend anything significant. Maybe a few cents?
As an aside: I am changing my opinion on static site generators.
They make things harder because you need to learn the generator syntax. The programming constructs in Hugo for example are woefully inadequate for anything serious. For example you can't parse a date as far as I can tell.
My solution for the next static project is to use the web framework I am used to (in my case ASP.NET MVC) and knock it up in that. I can use output caching and read from resource files to get the static site performance and not deal with a DB.
When I need to customize I will save a lot of time and frustration as I can just do what I need to do from experience.
